Abstract
Abstract In this paper, we have calculated an electron transmittance through Fe/GaAs/Fe in a magnetic tunnel junction (MTJ). The transmittance was computed by using the Airy wavefunction approach by considering the Dresselhaus effect. The calculated result shows that the electron transmittance for each spin state is different. The incident angle affects electron transmittance and electron polarization. It was also shown that electron polarization is also affected by the energy of the electron and the barrier width. Besides, the electron transmittance is quasisymmetric to the incident angle.
