Instability in domain wall dynamics in almost compensated ferrimagnets
R. V. Ovcharov, B. A. Ivanov, E. G. Galkina +2
Nanoscale self-localized topological spin textures, such as domain walls and skyrmions, are of interest for the fundamental physics of magnets and spintronics applications. Ferrima…
Emission of fast-propagating spin waves by an antiferromagnetic domain wall driven by spin current
Roman V. Ovcharov, B. A. Ivanov, Johan Åkerman +1
Antiferromagnets (AFMs) have great benefits for spintronic applications such as high frequencies (up to THz), high speeds (up to tens of km/s) of magnetic excitations, and field-fr…
Spin-Hall nanooscillator based on an antiferromagnetic domain wall
Roman V. Ovcharov, Elena G. Galkina, Boris A. Ivanov +1
We propose here a high-frequency spin-Hall nano-oscillator based on a simple magnetic texture, such as a domain wall, located in an antiferromagnet with easy-axis anisotropy type.…
Self-organization of topological defects for a triangular-lattice magnetic dots array subject to a perpendicular magnetic field
R. Khymyn, V. Kireev, B. Ivanov
The regular array of magnetic particles (magnetic dots) of the form of a two-dimensional triangular lattice in the presence of external magnetic field demonstrates complicated magn…
Ground states and magnetization process for an triangular lattice array of magnetic dots with perpendicular anisotropy
V. E. Kireev, R. S. Khymyn, B. A. Ivanov +1
We analyzed the ground state of the array of magnetic particles (magnetic dots) which form a two-dimensional triangular lattice, and magnetic moment of which is perpendicular to th…
Core-Core Dynamics in Spin Vortex Pairs
S. S. Cherepov, B. C. Koop, V. Korenivski +4
We investigate magnetic nano-pillars, in which two thin ferromagnetic nanoparticles are separated by a nanometer thin nonmagnetic spacer and can be set into stable spin vortex-pair…
