We report on the proximity effect in superconductor/ferromagnet bilayers made of a new combination of NbN for the superconductor and FeN for the ferromagnet. The bilayers were prepared by reactive magnetron sputtering on a thermally oxidized Si subst

We investigated high-frequency behavior of FeN thin films prepared by reactive sputtering through ferromagnetic resonance (FMR) and its relationship with the static magnetic properties. The FMR was observed in the frequency range from 2 to 18 GHz in

We have investigated the effect of temperature and bias current on the stability of the inverse spin-switch effect in Permalloy(Py)/Nb/Permalloy pseudo spin-valves. The inverse spin-switch operates between two orientations of the ferromagnetic moment

We have studied Hall effect for potassium (K)-doped BaFe2As2 superconducting thin films by analyzing the relation between the longitudinal resistivity (Pxx) and the Hall resistivity (Pxy). The thin films used in this study were fabricated on Al2O3 (0

We have investigated two switching mechanisms, the proximity effect and the influence of stray fields, in Permalloy (Py)/Nb/Py spin valves. Samples were grown by using dc magnetron sputtering and were patterned to form a bar shape. A coexistence of t

We investigated the flux-pinning properties of YBa2Cu3O7−x (YBCO) films in which Y2O3 and ZnO nanoparticles were uniformly embedded by using the pulsed laser deposition (PLD) technique. Y2O3 and ZnO nanoparticles with average sizes of 10–30 nm an

We studied the effect of domain wall pinning on the inverse spin-switch (ISS) behavior in pseudo spin-valve ferromagnet/superconductor/ferromagnet (F/S/F) trilayers. The deposited films were patterned to contain a micron-size triangular notch at thei
