Abstract
The anhysteretic remanent magnetization (ARM) and hysteresis parameters of synthetic, small, multidomain particles (0.2–0.4 μ) of Fe3O4 , dispersed at various concentrations in a non magnetic matrix (packing factors p = 0.01–0.3), have been measured. The coercive force Hc is weakly dependent on p. At higher concentrations the shape of the sample has a strong influence on the magnetization. There appears to be an additional concentration dependence of the ARM. However, the independence of partial ARMs also holds for larger p.
