A spin transistor consisting of a metallic giant magnetoresistance emitter, a copper base, and a p-n junction was discussed. It was observed that the emitter current changes from 1 mA at a magnetically parallel state to 0.968 mA at a magnetically antiparallel state. At the same states the base currents were found to be 29.3 μA and 333 nA, respectively, giving a magnetocurrent ratio of ∼8600% and a transfer ratio of 3×10-2 at room temperature for a common collector configuration. It was found that the sensivity of this spin device is higher than 4000 %/Oe.
