Anisotropic and controllable Gilbert-Bloch dissipation in spin valves
Akashdeep Kamra, Dmytro M. Polishchuk, Vladislav Korenivski +1
Spin valves form a key building block in a wide range of spintronic concepts and devices from magnetoresistive read heads to spin-transfer-torque oscillators. We elucidate the depe…
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…
Spin relaxation in multilayers with synthetic ferrimagnets
Dmytro M. Polishchuk, Taras I. Polek, Akashdeep Kamra +4
We demonstrate a strong tunability of the spin-pumping contribution to magnetic damping in a thin-film ferromagnetic free layer interfaced with a synthetic ferrimagnet (SFM), actin…
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…
Magnetic hysteresis in nanostructures with thermally-controlled RKKY coupling
D. M. Polishchuk, Yu. O. Tykhonenko-Polishchuk, V. Yu. Borynskyi +3
Mechanisms of the recently demonstrated ex-situ thermal control of the indirect exchange coupling in magnetic multilayer are discussed for different designs of the spacer layer. Te…
