The authors report magnetotransport evidence for the coexistence of a two-dimensional (2D) superconducting state and a 2D ferromagnetic state at the interface between amorphous CaZrO3 film and KTaO3 single crystal. Moreover, the magnetoresistance hysteresis reaches a maximum near the superconducting transition temperature.
