Zusammenfassung:•Temperature dependencies of the resistance of Al on YIG are studied.•R(T) variation with planar misalignment of current and Ms is found.•The combined action of current-generated and ferromagnet self-field is discussed. The superconductive phase transition in the aluminum film on top of the yttrium iron garnet single crystal has been studied. It is shown that the fall of resistance is observed at different temperatures depending on mutual orientation of current in a superconductive layer and magnetization in a ferrimagnet. The effect is discussed in terms of local superconductive ordering suppressed by both stray field from the ferrimagnet and self magnetic field of the current. The observed effect provides new ways to control conductivity using the plane wire patterning with different orientation of the circuit elements with respect to magnetization.
