We report here on in-plane anisotropy observed in the tunneling magnetoresistance of (Ga,Mn)As/n + -GaAs Esaki diode contacts and in the spin polarization generated in lateral all-semiconductor, all-electrical spin injection devices, employing such Esaki-diode structures as spin aligning contacts. T
