Abstract
The anisotropy field distribution is deduced in a number of magnetic record ing systems by the second derivative of the branch of the hysteresis curve in the range from saturation to remanence. The distributions so obtained ar e compared with statistical distribution functions. Generally, the beta or chi-squared distribution functions give the best fits for all samples. The dependence of the anisotropy held distribution on the interparticle interac tions and particle misorientation is also analyzed. (C) 1999 Elsevier Scien ce B.V. All rights reserved.
