摘要
PROBLEM TO BE SOLVED: To provide a magnetic thin film with which a high MR variation rate can be obtained.;SOLUTION: The magnetic thin film 15 has a pinned layer 7 whose magnetization direction is fixed with respect to an external magnetic field, a free layer 9 whose magnetization direction is changed according to the external magnetic field, and a spacer layer 8 which is sandwiched between the pinned layer 7 and the free layer 9. Sense current is configured to flow in a direction that is perpendicular to film surfaces of the pinned layer 7, spacer layer 8, and free layer 9. The spacer layer 8 has a CuZn metal alloy which includes an oxide region consisting of an oxide of any of Al, Si, Cr, Ti, Hf, Zr, Zn, and Mg.;COPYRIGHT: (C)2008,JPO&INPIT
