Abstract
In the present paper, the phase structure, magnetic properties, and magnetization reversal processes in the (Nd10Fe67B23)93Nb7 alloy ribbon were investigated. The X-ray diffraction analysis revealed a coexistence of the following phases: hard magnetic Nd2Fe14B, metastable soft magnetic Nd2Fe23B3, and paramagnetic Nd1+εFe4B4. Moreover, the changes in phase composition were noticed after heat treatment. In order to check magnetic measurements, the hysteresis loops were collected. The magnetization reversal curves were studied by constructing the reversible part of magnetization dependence on the irreversible part of magnetization. [ABSTRACT FROM AUTHOR]
