Measurement of Anisotropic Magnetoresistance in Fe,Co,Ni-Based Crystalline Alloys

Measured results for the ferromagnetic anisotropy of resistivity (FAR in Fe-Co-Ni and Co-Ni-transition metal crystalline alloys are reported. The FAR of Fe-Co-Ni alloys was found to exhibit a peak at the saturated magnetic moment η

of 0.8 to 1.0, differing from the behavior for amorphous material, and the largest FAR value was obtained for Co

alloy. The addition of a third transition metal to this alloy led to a decline in the FAR value in all cases; this decline is related to an increase in alloy resistivity.
