Abstract
The three-dimensional semi-infinite Ising-like ferromagnet, in which surface and bulk interactions may be different, is considered. The bulk and surface external magnetic fields are applied parallel to the magnetization. The response of a spin to small additional uniform magnetic field and the responses of a spin to small additional uniform magnetic fields applied in different planes parallel to the surface are studied. The analytical formulae for susceptibilities describing these responses are obtained. The Landau continuum theory is used. The effect of the surface field on the susceptibilities at temperatures below and close to the ordinary phase transition temperature is discussed.
