- Аннотация: Structure and magnetic hysteresis properties of (Nd0.55Ho0.45)2.7(Fe0.8Co0.2)14B1.2 nanocrystalline alloys, and their temperature and time stability is investigated. A nanosized structure was formed by subjecting ingots to melt spinning using a centrifugal method. Phase composition and structural peculiarities were controlled by X-ray diffraction and scanning electron microscopy. To investigate the stability of the magnetic hysteresis properties over time, the samples were kept at room temperature during several years. The magnetic performance was highly preserved. Hysteresis properties were found to be more sensitive to short heat treatments.
