  • Effective magnetization damping for a dynamical spin texture in metallic ferromagnet 
    Sukhostavets, O.V.; Gonzalez, J.M.; Guslienko, K.Y. (Физика низких температур, 2015)
    An additional magnetization damping for an inhomogeneous spin texture in metallic ferromagnets is calculated on the basis of the s–d exchange model. The effect of conduction electrons on the magnetization dynamics ...
  • Formation of Bose–Einstein magnon condensate via dipolar and exchange thermalization channels 
    Bozhko, D.A.; Clausen, P.; Chumak, A.V.; Kobljanskyj, Yu.V.; Hillebrands, B.; Serga, A.A. (Физика низких температур, 2015)
    Thermalization of a parametrically driven magnon gas leading to the formation of a Bose–Einstein condensate at the bottom of a spin-wave spectrum was studied by time- and wavevector-resolved Brillouin light scattering ...
  • Graded-index magnonics 
    Davies, C.S.; Kruglyak, V.V. (Физика низких температур, 2015)
    The wave solutions of the Landau–Lifshitz equation (spin waves) are characterized by some of the most complex and peculiar dispersion relations among all waves. For example, the spin-wave (“magnonic”) dispersion can range ...
  • Magnetic droplet solitons in orthogonal spin valves 
    Chung, S.; Mohseni, S.M.; Eklund, A.; Dürrenfeld, P.; Ranjbar, M.; Sani, S.R.; Nguyen, T.N.A.; Dumas, R.K.; Åkerman, J. (Физика низких температур, 2015)
    We review the recent experimental advancements in the realization and understanding of magnetic droplet solitons generated by spin transfer torque in orthogonal nanocontact based spin torque nanooscillators (STNOs) fabricated ...
  • Magnetic states in multiply-connected flat nanoelements 
    Bogatyrev, A.B.; Metlov, K.L. (Физика низких температур, 2015)
    Flat magnetic nanoelements are an essential component of current and future spintronic devices. By shaping an element it is possible to select and stabilize chosen metastable magnetic states, control its magnetization ...
  • Magnonic crystals — prospective structures for shaping spin waves in nanoscale 
    Rychły, J.; Gruszecki, P.; Mruczkiewicz, M.; Kłos, J.W.; Mamica, S.; Krawczyk, M. (Физика низких температур, 2015)
    We have investigated theoretically band structure of spin waves in magnonic crystals with periodicity in one(1D), two- (2D) and three-dimensions (3D). We have solved Landau–Lifshitz equation with the use of plane wave ...
  • Scattering of high-energy magnons off a magnetic skyrmion 
    Schroeter, S.; Garst, M. (Физика низких температур, 2015)
    We discuss the scattering of high-energy magnons off a single magnetic skyrmion within the field-polarized ground state of a two-dimensional chiral magnet. For wavevectors larger than the inverse skyrmion radius,krs>>1 ...
  • Thermoelectric spin transport through ferromagnetic heterostructures 
    Bender, S.A. (Физика низких температур, 2015)
    We study how spin is transferred by ferromagnetic dynamics in a charge insulator in response to a thermoelectric bias, which is established by supplying heat and/or spin accumulation via normal leads. At zero temperatur ...
  • Vortex-antivortex dynamics driven by spin-torque in a nanocontact 
    Zaspel, C.E.; Kireev, V.E. (Физика низких температур, 2015)
    A spin-polarized current in a nanocontact has been shown to induce the formation of a magnetic vortex at the nanocontact by the Oersted field, and spin-torque drives the vortex core in an elliptical orbit about the ...
  • Vortex dynamics in thin elliptic ferromagnetic nanodisks 
    Wysin, G.M. (Физика низких температур, 2015)
    Vortex gyrotropic motion in thin ferromagnetic nanodisks of elliptical shape is described here for a pure vortex state and for a situation with thermal fluctuations. The system is analyzed using numerical simulations of ...
  • Vortices in two-dimensional nanorings studied by means of the dynamical matrix method 
    Mamica, S. (Физика низких температур, 2015)
    This paper concerns an investigation of the spin wave excitations in magnetic nanoparticles. We provide a detailed derivation of the theoretical method for the determination of the normal modes of confined magnetic ...
  • Диссипативная функция ферромагнетика и теория кинетических уравнений Онcагера 
    Барьяхтар, В.Г.; Данилевич, А.Г. (Физика низких температур, 2015)
    Показано, что использование общей теории кинетических уравнений Онcагера позволяет построить модель диссипативной функции ферромагнетика и соответствующее релаксационное слагаемое в уравнении Ландау–Лифшица. Изложена ...
  • Модель обменного смещения в трехслойной структуре ФМ/АФМ/ФМ 
    Панкратова, М.Л.; Ковалев, А.С. (Физика низких температур, 2015)
    Теоретически исследованы особенности явления обменного смещения в трехслойных структурах ФМ/АФМ/ФМ, которые активно исследуются экспериментально. В рамках предложенной дискретной модели ферромагнитных слоев таких ...
