Antiferromagnet-mediated interlayer exchange: hybridization versus proximity effect
D. M. Polishchuk, Yu. O. Tykhonenko-Polishchuk, Ya. M. Lytvynenko +6
We investigate the interlayer coupling between two thin ferromagnetic (F) films mediated by an antiferromagnetic (AF) spacer in F*/AF/F trilayers and show how it transitions betwee…
Spin-wave Resonance in Arrays of Nanoscale Synthetic-antiferromagnets
Vladyslav Borynskyi, Dmytro Polishchuk, Iryna Sharai +4
The study concerns dynamics of standing spin waves in arrays of sub-100 nm elliptic synthetic-antiferromagnet (SAF) nanodisks. We performed a detailed ferromagnetic resonance analy…
Higher-order ferromagnetic resonances in periodic arrays of synthetic-antiferromagnet nanodiscs
V. Yu. Borynskyi, D. M. Polishchuk, A. K. Melnyk +3
We investigate spin dynamics in nanodisc arrays of synthetic-antiferromagnets (SAF) made of Py/NiCu/Py trilayers, where the NiCu spacer undergoes a Curie transition at about 200 K.…
Temperature and thickness dependent magnetostatic properties of [Fe/Py]/FeMn/Py multilayers
D. M. Polishchuk, O. I. Nakonechna, Ya. M. Lytvynenko +6
The magnetic properties of thin-film multilayers [Fe/Py]/FeMn/Py are investigated as a function of temperature and thickness of the antiferromagnetic FeMn spacer using SQUID magnet…
Magnetic proximity effect induced FMR frequency enhancement in {Py/FeMn} bilayers

Ferromagnetic resonance (FMR) in exchange-coupled ferromagnet-antiferromagnet (FM/AFM) bilayers commonly shows a moderate increase in the resonance frequency owing to the induced u…
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

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…
Current-driven thermo-magnetic switching in magnetic tunnel junctions
A. F. Kravets, D. M. Polishchuk, V. A. Pashchenko +2
We investigate switching of magnetic tunnel junctions (MTJs) driven by the thermal effect of the transport current through the junctions. The switching occurs in a specially design…
