Abstract
The low-field anhysteresis of small equidimensional multidomain particles of Fe3O4is found to be surprisingly large. For particle sizes below about 0.075 &m the anhysteretic susceptibility equals or surpasses that of elongated or doped equidimensional single-domain &Fe2O3particles used in conventional recording tapes.Keywords
