Abstract
The field and temperature dependences are studied on thermally demagne tized powder samples of BaO . 6Fe(2)O(3) with randomly oriented partic les. New aspects of magnetic behaviour of the small-particle system ha ve been revealed. The (H-T) diagram which reflects the role of the tem perature and field factors in the realization of three different magne tic states, the superparamagnetic included, is obtained in the tempera ture range of 300 K-T-c.
