用射频磁控溅射方法制备了一系列Co／Pb多层膜样品，进而研究了它的磁电阻与磁光性质．发现该系统除Co子层的各向异性磁电阻外还存在由反铁磁耦合导致的约为0．3％的巨磁电阻效应，以及磁光极克尔效应的增强现象，并对磁光增强的可能机制进行了研究． A series of samples of Co / Pb multilayers were prepared by radio frequency magnetron sputtering, and their magnetoresistance and magneto-optical properties were studied. It is found that in addition to the anisotropic magnetoresistance of the Co sublayer, the system also has the giant magnetoresistance effect of about 0.3% caused by the antiferromagnetic coupling and the enhancement phenomenon of the magneto-optic polar Kerr effect. The magneto-optical The possible mechanisms of enhancement were studied.
