We investigated the magnetic and dielectric properties of a metal (Pt)/insulator (Cr_2O_3)/magnetic floating gate (Fe)/tunnel layer (CeO_2)/semiconductor (Si) capacitor. This capacitor shows capacitance-voltage (C-V) properties typical of a Si Metal-Insulator-Semiconductor (MIS) capacitor with hysteresis, which indicates that electrons have been injected into the Fe layer. The capacitor also shows ferromagnetic properties. The C-V curve has a hysteresis window with a clockwise trace. This hysteresis behavior was changed by the application of an external magnetic field. These results indicate that this MIS capacitor contains a ferromagnetic floating gate and a ma...
