To be practically viable, a JD must operate at zero magnetic fields, exhibit high operating frequencies and efficiency, and possess tunability and scalability. In this study, we propose and experimentally demonstrate a straightforward mechanism that encompasses all these crucial features. Our approach involves utilizing an asymmetric Josephson junction with a magnetic weak link to attain a diode effect in the switching current.
