Recently, the superconducting diode effect (SDE) using a superconductor with zero electrical resistance has been attracting attention for its application to electronic circuits with very low energy loss. In this presentation, we report the successful control of infinite magnetoresistance and SDE using magnetization in a system where ferromagnetic Co is inserted into polar Nb/V/Ta multilayers showing remarkable SDE.
