“…Such phenomena as interlayer exchange coupling (IEC), giant magnetoresistance and elementary excitations [1][2][3][4][5][6][7] have been studied intensively, in contrary to basic magnetic properties of multilayers, to which much less attention have been paid [7][8][9]. In this paper we investigate magnetisation profiles and Curie temperature of bilayers with roughness in interface region.…”

The system of two magnetic (M) layers divided by nonmagnetic (N) spacer is considered. Roughness in interface region is introduced employing model proposed by Bruno and Chappert. Presence of roughness leads to modification of interface exchange parameter and interface anisotropy in comparison to samples with ideal interface. The magnetisation distribution and Curie temperature has been calculated using Green function formalism for systems consisting of Fe or Co standing for M and Cu or Au standing for N, respectively. Parameters corresponding to GaAs have been taken into account to characterize the substrate. The results obtained show decreasing of Curie temperature and shift of magnetisation curve with increasing of roughness parameter.

We report on the stabilization of ferromagnetic skyrmions in zero external magnetic fields, inexchange-biased systems composed of ferromagnetic-antiferromagnetic (FM-AFM) bilayers. By per-forming atomistic spin dynamics simulations, we study cases of compensated, uncompensated, andpartly uncompensated FM-AFM interfaces, and investigate the impact of important parameters suchas temperature, inter-plane exchange interaction, Dzyaloshinskii-Moria interaction, and magneticanisotropy on the skyrmions appearance and stability. The model with an uncompensated FM-AFMinterface leads to the stabilization of individual skyrmions and skyrmion lattices in the FM layer,caused by the effective field from the AFM instead of an external magnetic field. Similarly, in thecase of a fully compensated FM-AFM interface, we show that FM skyrmions can be stabilized. Wealso demonstrate that accounting of interface roughness leads to the stabilization of skyrmions both incompensated and uncompensated interfaces. Moreover, in bilayers with a rough interface, skyrmionsin the FM layer are observed for a wide range of exchange interaction values through the FM-AFMinterface, and the chirality of the skyrmions depends critically on the exchange interaction.
