Zusammenfassung:A mechanical model has been constructed as a means of understanding certain properties of anisotropic thin films. The model renders possible direction finding of the magnetization for a given amplitude and direction of the magnetic field vector lying in the plane of the film, provided rotational processes only are considered. The magnetic field is represented by the position of a small knob, and can be set in its amplitude and direction. A pointer then indicates the orientation of the magnetization vector. Jump phenomena can be easily observed, the locii of which form the critical curve for the uniaxial anisotropy.
