description: This work is devoted to the study of the magnetic properties of Europium orthoferrite EuFeO3 in connection with the relevance of the study of materials exhibit-ing the properties of multiferroics. Articles on the studies of europium orthoferrite EuFeO3 with the aim of studying the measurement procedure and identifying the features of this compound are considered. Dependences of the magnetic moment M on temperature and on the magnetic field were measured for micro and nano particles of europium orthoferrite. The measurements were carried out using a vibration magnetometer of the PPMS automated installation. The obtained dependencies are compared with published results. The obtained dependences were processed in order to separate the contributions to the total magnetic moment from different magnetization mechanisms. The effect of crystallite size on the magnetic characteristics of europium orthoferrite EuFeO3, in particular, on the appearance of a high coercivity of the hysteresis loops, was established. The results obtained are interesting both for determining the relationship between the magnetic characteristics and sizes and methods of producing nanocrystals, and for developing algorithms for separating the total dependence of M (H) on its constituent contributions from different magnetization mechanisms.
