Anisotropic magnetocapacitance in ferromagnetic-plate capacitors
Anisotropic magnetocapacitance in ferromagnetic-plate capacitors
The paper reports the observation of an anisotropic capacitance in a parallel plate $p$-$n$ junction capacitor where one plate is a ferromagnetic semiconductor, GaMnAs, and the other is nonmagnetic $n$-doped GaAs. The capacitance depends on the angle of the magnetization of the ferromagnetic plate and is analogous to the tunneling …
