Abstract

The effects of particle/particle interactions on the anhysteretic behavior of recording media have been investigated. The interactions were varied by changing the temperature at which the measurements were carried out, thereby decreasing the local magnetic order and consequently the interaction field strength. An increase in the anhysteretic susceptibility with increasing temperature was found experimentally. In some systems the change was up to 50% over the range 77 K\n\n\t\t
