In this work we focus on magnetic relaxation in Mn80Ir20(12 nm)/Cu(6 nm)/Py(dF) antiferromagnet/Cu/ferromagnet (AFM/Cu/FM) multilayers with different thickness of the ferromagnetic permalloy layer. An effective FM-AFM interaction mediated via the con

Isotropic FMR frequency enhancement in thin Py/FeMn bilayers under strong magnetic proximity effect

Autor: Vladislav Korenivski, A. I. Tovstolytkin, A. F. Kravets, V. Yu. Borynskyi, D. M. Polishchuk, T. I. Polek

Publikováno v: Journal of Physics D: Applied Physics. 54:305003

Exchange biasing in ferromagnet/antiferromagnet bilayers is known to enhance the material’s ferromagnetic resonance frequency and make it strongly angle dependent due to the unidirectional anisotropy induced at the interface. We observe a ten-fold

Spin relaxation in multilayers with synthetic ferrimagnets

Autor: Akashdeep Kamra, Vladislav Korenivski, D. M. Polishchuk, T. I. Polek, A. I. Tovstolytkin, A. F. Kravets, Arne Brataas

Publikováno v: Physical Review B. 98

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), acting as a spin-sink, via a thin Cu-spacer. The effect strongly depends on
