Magnetic skyrmions are nanoscale topological spin structures offering great promise for next-generation information storage technologies. The recent discovery of sub-100 nm room temperature (RT) skyrmions in several multilayer films has triggered vig

GeTe phase change material doped with 12 to 22 atomic percent TiO 2 were deposited and characterized. The crystallization of amorphous doped GeTe is inhibited by the incorporation of TiO 2 dopant up to 22 % as depicted by the increasing activation en

We experimentally investigated the influence of the location of nonmagnetic impurities (Au) inserted in the NiO layer of NiO/Co bilayers on the exchange bias. The inserted Au layer actually consists of a discontinuous plane of Au islands leading to l

Sputtered (Pt-Co)/sub n/-FeMn multilayers exhibit both perpendicular magnetic anisotropy and exchange bias at room temperature. Their magnetic properties after in-plane and perpendicular-to-plane magnetic annealing have been studied by means of extra

Bottom and top spin-valves comprising NiO as pinning layer were prepared by depositing the NiO layer either at normal or oblique incidence onto Si/SiO2 substrates. When the NiO layer is deposited at oblique incidence, a strong uniaxial anisotropy is
