| 摘要 |
The present invention relates to a magnetoresistive element including a first magnetic layer, a second magnetic layer, a first nonmagnetic layer, a third magnetic layer. The first magnetic layer includes a magnetic film of MnxGey (77 atm %≰x≰82 atm %, 18 atm %≰y≰23 atm %, x+y=100 atm %). The first nonmagnetic layer is provided between the first magnetic layer and the second magnetic layer. The third magnetic layer is provided between the first magnetic layer and the first nonmagnetic layer or between the second magnetic layer and the first nonmagnetic layer, or is provided between the first magnetic layer and the first nonmagnetic layer and between the second magnetic layer and the first nonmagnetic layer. The third magnetic layer includes a Heusler alloy. The present invention also relates to a magnetic memory containing the magnetoresistive element |
