CPP-TYPE MAGNETO RESISTIVE EFFECT ELEMENT HAVING A PAIR OF MAGNETIC LAYERS |
摘要 |
A magnetoresistance effect element comprises: a pair of magnetic layers whose magnetization directions form a relative angle therebetween that is variable depending on an external magnetic field; and a crystalline spacer layer sandwiched between the pair of magnetic layers; wherein sense current may flow in a direction that is perpendicular to a film plane of the pair of magnetic layers and the spacer layer. The spacer layer includes a crystalline oxide, and either or both magnetic layers whose magnetization direction is variable depending on the external magnetic field has a layer configuration in which a CoFeB layer is sandwiched between a CoFe layer and a NiFe layer and is positioned between the spacer layer and the NiFe layer.
