Abstract: Magnetic skyrmions are topologically protected domain structures related to the Dzyaloshinskii-Moriya interaction (DMI). To understand how magnetic skyrmions occur under different circumstances, we propose a model for skyrmion formation in a bilayer system of ferromagnetic/antiferromagnetic… read more here.

DOI: 10.1103/physrevb.101.174514
Abstract: We calculate the Andreev spectroscopy between a ferromagnetic lead and a Bi/Ni bilayer system. The bilayer system is described by the Anderson-Brinkman-Morel (ABM) state and mixing ABM and $S$-wave states. In both the ABM state… read more here.
