Individuals, Institutions and Discourses: Knowledge and Power in Russia's Iranian Studies of the Late Imperial, Soviet and Post-Soviet Periods

The scholarship on late Imperial Russia's Oriental studies is divided by a disagreement over the applicability of Edward Said's Orientalism to the Russian case. Moreover, in a broader sense, since the mid 1990s, Western scholarship has not been unanimous on the applicability of the underlying Foucauldian notions to late Imperial and Soviet Russia. While presenting a systematic study of Soviet and post-Soviet scholarship (mostly unfamiliar to Western readership), this article offers an assessment of the institutional and individual practices adopted within Russia's Oriental studies from the late nineteenth century to the present. The article aims to provide an analysis that goes far beyond the Saidian restrictive East-West dichotomy and his concept of two-vector relations between knowledge and state power. It offers a new reading, based on the deconstruction of the interplay of the manifold multi-vector power/knowledge relations that is clearly identifiable in Russia's long twentieth-century Iranian studies

Persian Studies and the Military in Late Imperial Russia (1863-1917): State Power in the Service of Knowledge?

This article pursues the goal of going beyond Saidian notions of Orientalism and Said's assumption of the “complicity of knowledge with power” to reach back to Foucault's initial postulations on the role of institutions and the intellectual in the interplay of power/knowledge relations. The article concentrates on the role of Russian military Oriental studies institutions and Orientologists in the context of discourses (the promotion of Russkoe Delo, the juxtaposition of Russia with the West and the Orient, etc.) that existed in late Imperial Russia and influenced the accumulation and development of scholarly knowledge on the Orient. Therefore, the significant contribution of the military domain to Russian Oriental studies on both the institutional and individual levels are examined from the angle of intra-Russian discourses in the period from the establishment of the Asiatic Section of the General Staff in 1863 up to 1917.</jats:p

Rupture or Continuity? The organisational set-up of Russian/Soviet Oriental Studies before and after 1917:Special Issue

The article presents a systematic appraisal of the essential Russian- and English-language scholarship on Russian Oriental studies and particularly on Russia's Iranology. However, the main target of this article is to trace the discursive continuities and epistemological shifts which have existed in late imperial, Soviet and, partially, post-Soviet Russia's Oriental studies since the end of the nineteenth century. Drawing on the sources of the main Russian political, military and academic archives, the article offers an assessment of the question of rupture or continuity, which is based on a synthesis of the above-mentioned scholarship from an entirely new angle. Dealing with the seemingly overwhelming watershed of 1917, an analysis is provided that transcends the unhelpful continuity/change dichotomy, putting forward a new interpretation, which is informed by the Foucauldian conceptualization of the productive nature of the power/knowledge nexus

Fundamentals of Curvilinear Ferromagnetism: Statics and Dynamics of Geometrically Curved Wires and Narrow Ribbons

Low-dimensional magnetic architectures including wires and thin films are key enablers of prospective ultrafast and energy efficient memory, logic, and sensor devices relying on spin-orbitronic and magnonic concepts. Curvilinear magnetism emerged as a novel approach in material science, which allows tailoring of the fundamental anisotropic and chiral responses relying on the geometrical curvature of magnetic architectures. Much attention is dedicated to magnetic wires of Möbius, helical, or DNA-like double helical shapes, which act as prototypical objects for the exploration of the fundamentals of curvilinear magnetism. Although there is a bulk number of original publications covering fabrication, characterization, and theory of magnetic wires, there is no comprehensive review of the theoretical framework of how to describe these architectures. Here, theoretical activities on the topic of curvilinear magnetic wires and narrow nanoribbons are summarized, providing a systematic review of the emergent interactions and novel physical effects caused by the curvature. Prospective research directions of curvilinear spintronics and spin-orbitronics are discussed, the fundamental framework for curvilinear magnonics are outlined, and mechanically flexible curvilinear architectures for soft robotics are introduced

Unidirectional tilt of domain walls in equilibrium in biaxial stripes with Dzyaloshinskii–Moriya interaction

The orientation of a chiral magnetic domain wall in a racetrack determines its dynamical properties. In equilibrium, magnetic domain walls are expected to be oriented perpendicular to the stripe axis. We demonstrate the appearance of a unidirectional domain wall tilt in out-of-plane magnetized stripes with biaxial anisotropy and Dzyaloshinskii–Moriya interaction (DMI). The tilt is a result of the interplay between the in-plane easy-axis anisotropy and DMI. We show that the additional anisotropy and DMI prefer different domain wall structure: anisotropy links the magnetization azimuthal angle inside the domain wall with the anisotropy direction in contrast to DMI, which prefers the magnetization perpendicular to the domain wall. Their balance with the energy gain due to domain wall extension defines the equilibrium magnetization the domain wall tilting. We demonstrate that the Walker field and the corresponding Walker velocity of the domain wall can be enhanced in the system supporting tilted walls

Localization of magnon modes in a curved magnetic nanowire

Spin waves in magnetic nanowires can be bound by a local bending of the wire. The eigenfrequency of a truly local magnon mode is determined by the curvature: a general analytical expression is established for any infinitesimally weak localized curvature of the wire. The interaction of the local mode with spin waves, propagating through the bend, results in scattering features, which is well confirmed by spin-lattice simulations.Comment: ReVTeX4-1: 11 pages, 4 figure
