Abstract:

The magnetic structure transformation of the layered ferrimagnet {[}Co/Gd36Co64](4)/Co in an external magnetic field was comprehensively studied. Using magnetometrical, magnetooptical, and magnetoresistive techniques, it is established that, when magnetized in fields exceeding a threshold value H-cr, the collinear magnetic structure formed by the magnetic moments of the Co and GdCo layers is distorted. The value H-cr varies nonmonotonically with temperature T and reaches a minimum at the temperature of magnetic compensation of the layered ferrimagnet. The H-cr(T) dependence is well described in terms of the homogeneous ferrimagnet model with an adequately chosen phenomenological intersublattice interaction constant taking into account the weakened coupling of the surface Co layers with the internal part of the actual layer structure.
