Spin-polarized transport in a full magnetic pn tunnel junction

Simulations of the tunneling current as a function of voltage and temperature for a Zener diode where both sides are ferromagnetic have been performed. The current is evaluated as a function of the applied bias, the magnetization, and the temperature on the diode. The tunneling magnetoresistance is also analyzed. Mn doped GaAs parameters were used to simulate a highly asymmetric doped diode, which leads to a large difference on the magnetization values between the p and n sides.
