Magnetoresistance Effect in Ni-Fe Thin Films Measured by Use of a High Magnetic Field

The anisotropic magnetoresistance (MR) effect, galvano- magnetic electromotive force effect, and forced MR effect in Ni-Fe thin films were studied by using high magnetic fields up to 15 T. These effects were measured in Ni-Fe thin films with various Ni compositions. The quantitative investiga- tion of the anisotropic MR effect and forced MR effect indicated that the dependence of the composition on the characterization of the anisotropic MR effect was similar to that of the forced effect. It was also found that the composition‘s dependence on the characterization of the forced effect had an additional peak around Ni0.5Fe0.5,which was not observed in the composition dependence of the anisotropic MR effect.
