    This qualitative study identified the formal and informal performance management (PM) practices in use in Australian public universities for academic staff Levels A, B and C. It asked the following research questions. • What PM practices are currently in use in these universities? • What are the similarities in approach and what issues does PM raise? • How do academic staff who take part in these practices (as either staff or management) experience them? • What cultural and contextual factors (if any) contribute to this experience? • What are the perceived effects of these practices on the performance of individuals, teams and the organisation? • Which system elements do academic staff and academic managers perceive to be most effective in academic cultures and why? The context of substantive change within Australian universities was outlined and literature pertaining to the field of PM in general, and in educational organisations in particular, was explored. The existence, structure, purposes and other factual details of formal PM systems were identified, although the study focused on the opinions, perceptions and attitudes of the respondents. Findings suggested that current PM practice in Australian public universities did little to meet the needs of any of the key stakeholders and remained fundamentally unsatisfying to all concerned. Furthermore, the failure to clearly articulate the purposes and to consider the implementation and ongoing costs of a formal PM system typically resulted in widespread cynicism and a ritual dance of compliance that demonstrated palpably low engagement with systems. Formal PM systems helped to clarify objectives and workload allocation for some staff, but were found to be poorly linked to organisational planning processes, poor at differentiating levels of performance, not valued by academic staff as a vehicle for meaningful feedback, failing to follow through on development outcomes and thus did little to build team, individual or organisational capability. Study recommendations suggested that developmental models of PM were more appropriate and acceptable in academia and that considerable work would be required to incorporate evaluative links such as performance-related pay successfully. More rigorous evaluation, consultation processes regarding user preferences, piloting of PM systems prior to full implementation, and dedicated resources for the PM function and its outcomes (such as staff development), would be required as a part of a comprehensive change management strategy to overcome historical resistance. A thorough capability analysis of the people management skills for Heads of School and above was seen as a priority, given that feedback skill and the management of under-performance were consistently identified as problematic. The costs of under-performance warranted this expenditure. A national evaluation study of PM practice in higher education was recommended to assess the real outcomes, costs and benefits and determine whether continued investment in PM systems was actually merited. Alternative models and approaches such as modular PM systems for the different stages of an academic career, promotion portfolios, reflective practice or peer learning groups were suggested as potentially more successful in enhancing the accountability and performance of academic staff than mandated hierarchical PM

    Co(acac)2(H2O)2 (1, acac = acetylacetonate), a transition metal complex (S = 3/2), displays field‐induced slow magnetic relaxation as a single‐molecule magnet. For 1 and its isotopologues Co(acac)2(D2O)2 (1‐d4) and Co(acac‐d7)2(D2O)2 (1‐d18) in approximately D4h symmetry, zero‐field splitting of the ground electronic state leads to two Kramers doublets (KDs): lower energy MS = ±1/2 (ϕ1,2) and higher energy MS = ±3/2 (ϕ3,4) states. This work employs inelastic neutron scattering (INS), a unique method to probe magnetic transitions, to probe different magnetic excitations in 1‐d4 and 1‐d18. Direct‐geometry, time‐of‐flight Disk‐Chopper Spectrometer (DCS), with applied magnetic fields up to 10 T, has been used to study the intra‐KD transition as a result of Zeeman splitting, MS = –1/2 (ϕ1) → MS = +1/2 (ϕ2), in 1‐d18. This is a rare study of the MS = –1/2 → MS = +1/2 excitation in transition metal complexes by INS. Indirect‐geometry INS spectrometer VISION has been used to probe the inter‐KD, ZFS transition, MS = ±1/2 (ϕ1,2) → MS = ±3/2 (ϕ3,4) in both 1‐d4 and 1‐d18, by variable‐temperature (VT) properties of this excitation. The INS spectra measured on VISION also give phonon features of the complexes that are well described by periodic DFT phonon calculations

    A combination of inelastic neutron scattering (INS), far-IR magneto-spectroscopy (FIRMS), and Raman magneto-spectroscopy (RaMS) has been used to comprehensively probe magnetic excitations in Co(AsPh3)2I2 (1), a reported single-molecule magnet (SMM). With applied field, the magnetic zero-field splitting (ZFS) peak (2Dâ€Č) shifts to higher energies in each spectroscopy. INS placed the ZFS peak at 54 cm–1, as revealed by both variable-temperature (VT) and variable-magnetic-field data, giving results that agree well with those from both far-IR and Raman studies. Both FIRMS and RaMS also reveal the presence of multiple spin–phonon couplings as avoided crossings with neighboring phonons. Here, phonons refer to both intramolecular and lattice vibrations. The results constitute a rare case in which the spin–phonon couplings are observed with both Raman-active (g modes) and far-IR-active phonons (u modes; space group P21/c, no. 14, Z = 4 for 1). These couplings are fit using a simple avoided crossing model with coupling constants of ca. 1–2 cm–1. The combined spectroscopies accurately determine the magnetic excited level and the interaction of the magnetic excitation with phonon modes. Density functional theory (DFT) phonon calculations compare well with INS, allowing for the assignment of the modes and their symmetries. Electronic calculations elucidate the nature of ZFS in the complex. Features of different techniques to determine ZFS and other spin-Hamiltonian parameters in transition-metal complexes are summarized

    Spin–phonon coupling plays an important role in single-molecule magnets and molecular qubits. However, there have been few detailed studies of its nature. Here, we show for the first time distinct couplings of g phonons of CoII(acac)2(H2O)2 (acac = acetylacetonate) and its deuterated analogs with zero-field-split, excited magnetic/spin levels (Kramers doublet (KD)) of the S = 3/2 electronic ground state. The couplings are observed as avoided crossings in magnetic-field-dependent Raman spectra with coupling constants of 1–2 cm−1. Far-IR spectra reveal the magnetic-dipole-allowed, inter-KD transition, shifting to higher energy with increasing field. Density functional theory calculations are used to rationalize energies and symmetries of the phonons. A vibronic coupling model, supported by electronic structure calculations, is proposed to rationalize the behavior of the coupled Raman peaks. This work spectroscopically reveals and quantitates the spin–phonon couplings in typical transition metal complexes and sheds light on the origin of the spin–phonon entanglement
