The antecedents of direct management communication to employees in Mauritius
We measure whether, in a developing country, existence of a ‘hard’ strategic human resource management (SHRM) strategy developed at high organizational levels or one designed to enhance employee knowledge inputs and thereby promote employer–employee interdependence (EEIN) is a stronger antecedent of direct communication to employees. We use data from a comprehensive survey of HR practices in Mauritius,
one of Africa’s most open and successful economies. We find that both SHRM and EEIN are antecedents, but that the latter is stronger in public organizations and in smaller and older companies. We conclude that EEIN is a significant analytic category for explaining management practices especially in a historic sense in this and possibly other developing country contexts
Management communication, unionization, FDI and company performance in a developing country
Purpose – The purpose of this paper is to examine the associations between management direct communication to employees, unionization, foreign direct investment (FDI) and company performance in Mauritius, Africa’s most successful economy.
Design/methodology/approach – The authors use firm data from a survey conducted in Mauritius in late 2011. The authors conduct regression analysis to study the relationship between direct
communication, unionization and performance conditional on ownership type.
Findings – Mauritian labour unions, in common with their counterparts from mainland Africa, are strongest in the public sector. They have been characterized as weak and lacking in influence on management. Yet the authors find a strong association between unionization and management communication in the private sector. The authors also find a positive association between direct communication and company performance which the authors argue is likely to be an indirect consequence of unionization. FDI shows no particular effects.
Research limitations/implications – It appears that the consequences of union presence transcend pay and conditions. The effects are unexpectedly marked, particularly when the stress by some authors on union weakness in the private sector is taken into account.
Originality/value – It may be that local unions’ strong focus on the enterprise – a form of representation favoured by US-based multinational companies, constitutes a strength in stimulating
management communication to employees by focusing union activities at that level. Whilst the authors have suggested that this is unlikely to be primarily a result of conscious union strategy, the enterprise focus may serve to buttress existing employee attitudes. In any event, unionization is certainly closely associated in this African country with a practice that is linked to positive economic
effects at the enterprise level.

Quantitative characterization of spin-orbit torques in Pt/Co/Pt/Co/Ta/BTO heterostructures due to the magnetization azimuthal angle dependence
Substantial understanding of spin-orbit interactions in heavy-metal (HM)/ferromagnet (FM)heterostructures is crucial in developing spin-orbit torque (SOT) spintronics devices utilizing spin Hall and Rashba effects. Though the study of SOT effective field dependence on the out-of-plane magnetization angle has been relatively extensive, the understanding of in-plane magnetization angle dependence remains unknown. Here, we analytically propose a method to compute the SOT effective fields as a function of the in-plane magnetization angle using the harmonic Hall technique in perpendicular magnetic anisotropy (PMA) structures. Two different samples with PMA, a Pt/Co/Pt/Co/Ta/BaTi O3 (BTO) test sample and a Pt/Co/Pt/Co/Ta reference sample, are studied using the derived formula. Our measurements reveal that only the dampinglike field of the test sample with a BTO capping layer exhibits an in-plane magnetization angle dependence, while no angular dependence is found in the reference sample. The presence of the BTO layer in the test sample, which gives rise to a Rashba effect at the interface, is ascribed as the source of the angular dependence of the dampinglike field
Field-free spin-orbit torque switching of a perpendicular ferromagnet with Dzyaloshinskii-Moriya interaction
Leveraging on interfacial Dzyaloshinskii-Moriya interaction (DMI) induced intrinsic magnetization tilting in nanostructures, a parametric window enabling field-free spin-orbit torque (SOT) magnetization switching in a perpendicular ferromagnet is established. The critical current density (Jc) bounds for SOT switching are highly dependent on the DMI, producing a distorted diamond-shaped region bounded by the Jc-DMI curves. The widest Jc interval is found for DMI values between 0.5 mJ/m2 and 0.8 mJ/m2. Geometrical modulation, of the ferromagnetic layer, reveals that the circular structure is optimum for minimizing the switching energy while maximizing the parametric window. For all the structures investigated, the SOT induced reversal process is via domain wall nucleation and propagation, and the switching is practical at room temperature
Deterministic Spin-Orbit Torque Induced Magnetization Reversal In Pt/[Co/Ni]<sub>n</sub>/Co/Ta Multilayer Hall Bars
Spin-orbit torque (SOT) induced by electric current has attracted extensive attention as an efficient method of controlling the magnetization in nanomagnetic structures. SOT-induced magnetization reversal is usually achieved with the aid of an in-plane bias magnetic field. In this paper, we show that by selecting a film stack with weak out-of-plane magnetic anisotropy, field-free SOT-induced switching can be achieved in micron sized multilayers. Using direct current, deterministic bipolar magnetization reversal is obtained in Pt/[Co/Ni]2/Co/Ta structures. Kerr imaging reveals that the SOT-induced magnetization switching process is completed via the nucleation of reverse domain and propagation of domain wall in the system

Spin orbit torque induced asymmetric depinning of chiral Néel domain wall in Co/Ni heterostructures
In this letter, we report on distinct depinning of a chiral Néel domain wall (DW) driven by spin-orbit torque (SOT) in Co/Ni nanowires with symmetric potential barriers. In these structures, DW propagation was shown to be in the opposite direction to the electron flow as evidenced from current assisted DW depinning measurements. A transition from field dominated DW depinning to SOT dominated DW depinning was observed as the bias current was increased. For SOT dominated DW depinning, the Up-Down DW exhibits a larger depinning field as compared to the Down-Up DW. This is attributed to the interplay between the SOT and Dzyaloshinskii-Moriya interaction in the structure
Asymmetrical domain wall propagation in bifurcated PMA wire structure due to the Dzyaloshinskii-Moriya interaction
Controlling domain wall (DW) motion in complex magnetic network structures is of paramount significance for the development of spin-based devices. Here, we report on the dynamics of a propagating DW in a bifurcated ferromagnetic wire with perpendicular magnetic anisotropy (PMA). The Dzyaloshinskii-Moriya interaction (DMI) in the wire structure induces a tilt angle to the injected DW, which leads to a quasi-selective propagation through the network branch. The DW tilting causes a field interval between DWs to arrive at Hall bars in the individual branches. Micromagnetic results further show that by tailoring the strength of the DMI, the control of DW dynamics in the PMA complex network structures can be achieved
