ABSTRACT:
A MR element which has a basically three-layered structure wherein the first and the second magnetic layer sandwich the nonmagnetic layer or of a basically five-layered structure wherein nonmagnetic layers are sandwiched between the first and second magnetic layers and between the second and third magnetic layers, respectively. The MR element of such arrangement offers a surprisingly large MR ratio under application of a sufficiently low magnetic field despite such a simple arrangement thereof.
