摘要：
A spin filter is composed of a first magnetic semiconductor multi-quantum well structure, a second magnetic semiconductor multi-quantum well structure and a non-magnetic semiconductor quantum well structure which is located between the first magnetic semiconductor multi-quantum well structure and the second magnetic semiconductor multi-quantum well structure. The first magnetic semiconductor multi-quantum well structure and the second magnetic semiconductor multi-quantum well structure are split in spin state. Carriers in down-spin state are penetrated through the first magnetic semiconductor multi-quantum well structure and carriers in up-spin state are penetrated through the second magnetic semiconductor multi-quantum well structure.
