dc.description.abstractOrigin of the intrinsic coercivity field variations observed by hysteretic measurements established by Nikolic et al. was investigated in detail by ZFC/FC measurements. In this study, magnetic behavior of the samples is further examined by calculation of the ZFC Mn(T) and Mn(H) first derivatives. Performed study showed that the main contribution to the measured coercivity comes from the ε-Fe2O3 particles, characterized by Hci = 24 kOe, although both samples posses SPM ε-Fe2O3 fraction. As a result, Hci values of the samples are differed dependent on the quantity of the SPM ε-Fe2O3 particles in the sample. Mechanism of the intrisic coercivity field variations is discussed. © 2019, Pleiades Publishing, Ltd.en
