摘要
It is found that the exchange interaction of Co (5 nm) ferromagnetic layers via Pd in Co/Pd multilayer films and of Co (5 nm) and CoNi (5 nm) layers via the same nonmagnetic metal in Co/Pd/CoNi films can be both ferro-and antiferromagnetic. The period of the AF-F-AF oscillations is of the order of 0.8 nm, and the amplitude of the oscillations decays as a power-law function similar to d(Pd)(-2). (C) 1997 American Institute of Physics.
