Abstract
The dependence of the coercivity, H c, remanence coercivity, H R, and remanence, M R, on particle size has been investigated at various temperatures from 77°K to 297°K. The results show that H c and H R increase as the particle size and temperature decrease. There is strong evidence for the existence of a critical particle size ∼45 μm below which the coercivities H c and H R increase very rapidly. This is also supported by the observation that there is an abrupt increase in the remanence, M R, at a particle size ∼45 μm.Keywords
