A spin tunneling transistor (STT) was-designed by growing a magnetic tunneling junction (MTJ) on a p-n junction. The magnetocurrent (MC) ratio of the collector can be stabilized roughly above 40% at V-E = 1.25 +/- 0.25 V with the transfer ratio (I-C/I-E) of 2.88%, while the transistor is operated in the common collector circuitry. with an emitter bias and a base resistor at room temperature. The output current can be more than 4 mu A when the magnetic moment of the base layer is oriented parallel to that of the emitter layer. The high performance is achieved mainly due to the base resistor, which can push our STT to the right working region and enlarge the MC ratio of the collector.
