摘要：

Room temperature transport properties of two sets of CIP spin valve structures were studied. In addition to the conventional collinear four-probe technique, the dependence of the resistivity on the angle between the magnetizations of the free and pinned Py layers has been studied. We have shown that this approach allows one to separate the contributions of giant magnetoresistance, the anisotropic magnetoresistance and the nonmagnetic resistivity, which is not possible by using the conventional four-probe method.
