Tunneling anisotropic magnetoresistance effect in p+(Ga,Mn)As/n+GaAs Esaki diode

Ciorga, Mariusz ; Einwanger, Andreas ; Sadowski, J. ; Wegscheider, Werner ; Weiss, Dieter


We have performed magnetotransport experiments on p+-(Ga,Mn)As/n+-GaAs Esaki diode devices. The spin-valve-like signal was observed in these devices in an in-plane magnetic field configuration due to Tunneling Anisotropic Magnetoresistance effect. The pattern of the observed magnetic reversal process strongly depends on the observed magnetic anisotropy of the (Ga,Mn)As layer - depending on its ...
