摘要：

We present a model for calculating the tunneling conductance and thus the tunneling magnetoresistance for MgO-based magnetic tunneling junctions. Both effects from the interface scattering and the barrier imperfection are considered in the model by introducing additional parameters. The temperature dependence of resistance is included by using a phenomenological model. This model successfully interprets the experimental results in the published literatures.
