Abstract :
Mean-field continual model of Ruderman-Kittel-Kasuya-Yosida (RKKY) magnetism in thin films and wires is considered. The spatial distribution of the magnetization is described by the nonlinear integral equation. The magnetization distribution over the film thickness or the wire diameter is close, correspondingly, to the parabolic or Gaussian one. The dependence of the Curie temperature on the film thickness, and temperature dependencies of the average film and wire magnetizations are determined.
