A new multilayer system: Pd1-xCox Ag
Résumé
In Co0.3Pd0.7 Ag superlattices grown by molecular beam epitaxy, we have observed a crossover from out- to in-plane magnetization for CoPd thicknesses below 50 m̊A and found a magnetoresistance of 13% at 4.2 K correlated with an antiferromagnetic alignment between successive CoPd magnetic layers.
