摘要
The temperature dependence of the interlayer coupling of perpendicularly magnetized Ni/Cu/Ni(001) trilayers is studied. A crossover in the alignment of the sublayer magnetizations from parallel to antiparallel is observed with increasing temperature, although the interlayer exchange is measured to be antiferromagnetic for all temperatures. The crossover is the result of the competition between the antiferromagnetic interaction and the magnetic anisotropy energy. This Ni/Cu/Ni trilayer with moderate exchange coupling serves as a model for magnetic multilayers in which the interlayer coupling can be switched with temperature.
