Аннотация: We studied the temperature dependence of the critical current density, JcS/I/F(T), of a Nb/SiO2/PdNi trilayers before and after the magnetization of the PdNi layers in both out of plane and in plane directions. Nb and PdNi thin films interact via the electromagnetic coupling. We show that after the out of plane magnetization the magnitudes of critical current density become minimal far below the critical temperature Tc, while close to Tc the difference in magnitudes of JcS/I/F weakly depends on directions of magnetization. This effect is discussed in terms of spontaneous vortex – antivortex pairs induced in Nb thin film due to the electromagnetic coupling with the PdNi layer.
