Abstract

The behavior of prolate spheroidal particles, corresponding to the acicular particles found in magnetic recording media is analyzed. Both experimental and theoretical investigations have been carried out to understand and optimize magnetic materials. A problem is the magnetization reversal mode for even the simplest system, a particle small enough consisting in a single magnetic domain..

Keywords

Elongated particles, Magnetic recording media, Magnetization reversal processes.
