Abstract

A recording medium consisting of a dispersion of cobalt nanocrystallites is produced by the controlled rapid thermal decomposition of cobalt nitride films. Blocking temperature measurements in conjunction with transmission electron microscopy determine the particle size and distribution. Isothermal and DC remanence curves are used to determine the nature and degree of particle-particle interactions
