摘要：

The resistivity and giant magnetoresistance (GMR) of(Cu3Ni3)(n) embedded in Cu(100), for n less than or equal to II, that originates from the electronic structure of these finite, yet otherwise perfect, systems is calculated for currents in the plane of the layers (CIP) by using the Kubo-Greenwood formula for semi-infinite systems and the fully relativistic, spin-polarized screened Korringa-Kohn-Rostoker method. We find that for this particular type of repeated structure the CIP resistivity decreases from about 6 to 2 mu Omega cm as the number of repeats increases from 2 to 11, and the CIP-GMR while starting out at 4% for n=2 goes up to 16% at n=11.
