  • Abstract
    A theory is set up to calculate anisotropy fields in assemblies of fine magnetic particles from remanence curves. The formalism takes into account the effects of thermal fluctuations. With the help of this approach anisotropy fields of microcrystalline and nanocrystalline bariumhexaferrite particles are determined
