Abstract

The anisotropy field distribution is deduced in a number of magnetic recording systems by the second derivative of the branch of the hysteresis curve in the range from saturation to remanence. The distributions so obtained are 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 field distribution on the interparticle interactions and particle misorientation is also analyzed.
