Stabilization of magnetic skyrmions by RKKY interactions
Alla V. Bezvershenko, Alexei K. Kolezhuk, Boris A. Ivanov
We study the stabilization of an isolated magnetic skyrmion in a magnetic monolayer on a nonmagnetic conducting substrate via the Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange inte…
Exchange relaxation as the mechanism of ultrafast spin reorientation in two-sublattice ferrimagnets
V. G. Baryakhtar, V. I. Butrim, B. A. Ivanov
In the exchange approximation, an exact solution is obtained for the sublattice magnetizations evolution in a two-sublattice ferrimagnet. Nonlinear regimes of spin dynamics are fou…
Inertial longitudinal magnetization reversal for non-Heisenberg ferromagnets
E. G. Galkina, V. I. Butrim, Yu. A. Fridman +2
We analyze theoretically the novel pathway of ultrafast spin dynamics for ferromagnets with high enough single-ion anisotropy (non-Heisenberg ferromagnets). This longitudinal spin…
Spectral dependence of photoinduced spin precession in DyFeO3
Ryugo Iida, Takuya Satoh, Tsutomu Shimura +4
Spin precession was nonthermally induced by an ultrashort laser pulse in orthoferrite DyFeO3 with a pump-probe technique. Both circularly and linearly polarized pulses led to spin…
Spin Oscillations in Antiferromagnetic NiO Triggered by Circularly Polarized Light
Takuya Satoh, Sung-Jin Cho, Ryugo Iida +7
Coherent spin oscillations were non-thermally induced by circularly polarized pulses in fully compensated antiferromagnetic NiO. This effect is attributed to an entirely new mechan…
Quantum effects for the 2D soliton in isotropic ferromagnets
Boris A. Ivanov, Denis D. Sheka, Vasilii V. Krivonos +1
We evaluate a zero-point quantum correction to a Belavin-Polyakov soliton in an isotropic 2D ferromagnet. By revising the scattering problem of quasi-particles by a soliton we show…
