Effects of asymmetry in strongly coupled spin vortex pairs
E. Holmgren, M. Persson, V. Korenivski
Effects of magnetic asymmetry on strongly coupled spin-vortex pairs with parallel core polarization and antiparallel chirality in synthetic nanomagnets are investigated. This inclu…
Giant magnetocaloric effect driven by indirect exchange in magnetic multilayers
D. M. Polishchuk, Yu. O. Tykhonenko-Polishchuk, E. Holmgren +3
Indirect exchange coupling in magnetic multilayers, also known as the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, is known to be highly effective in controlling the interlaye…
Transient dynamics of strongly coupled spin vortex pairs: effects of anharmonicity and resonant excitation on inertial switching
E. Holmgren, A. Bondarenko, M. Persson +2
Spin vortices in magnetic nanopillars are used as GHz oscillators, with frequency however essentially fixed in fabrication. We demonstrate a model system of a two-vortex nanopillar…
Chaotic dynamics in spin-vortex pairs
A. V. Bondarenko, E. Holmgren, Z. W. Li +2
We report on spin-vortex pair dynamics measured at temperatures low enough to suppress stochastic core motion, thereby uncovering the highly non-linear intrinsic dynamics of the sy…
