Abstract The magnetic behaviour of polycrystalline materials is closely related to their specific manufacturing process. Beside composition, the various factors that affect this behaviour and cause the particular microstructure of these materials include non-magnetic inclusions, grain size, pressing, temperature, sintering time, and cooling rate. A study has been done of magnetization curves and static hysteresis loops in a set of polycrystalline nickel ferrites. The experimental results were fitted by a second-order rational function, which easily allowed us to calculate their characteristic parameters, and analyze them according to the non-magnetic inclusions model.
