Аннотация: The dependence of the exchange bias of epitaxial single-crystal Co/Cu/CoO trilayer films on the copper layer thickness and temperature is studied. The exchange bias of the hysteresis loops of the ferromagnetic cobalt layer as a function of the copper layer thickness is found to have a well-pronounced oscillating character. The osciПоказать полностьюllations manifest themselves over the entire temperature range in which an exchange bias takes place (77-220 K). The complex variation of the oscillation amplitude with the nonmagnetic layer thickness can be explained by the superposition of two interlayer exchange coupling oscillation periods (lambda(1) a parts per thousand 10-11 , lambda(2) a parts per thousand 20 ) having differentamplitudes and temperature dependences.
