Wang, Jinke TangTunneling magnetoresistance TMR in Ga0.92Mn0.08As/Al–O/Co40Fe40B20 trilayer hybrid structure as a function of temperature from 10 to 50 K with magnetic field |H|≤ 2000 Oe has been studied. TMR ratio of 1.6% at low fields at 10 K was achieved with the applied current of 1 μA. The behavior of junction resistance was well explained by the tunneling resistance across the barrier. Strong bias dependences of magnetoresistance and junction resistance were presented.
