Development of nanostructured magnetic materials based on high-purity rare-earth metals and study of their fundamental characteristics

Popis výsledku v původním jazyce

The effect of the structural state on magnetic and hysteretic properties of compounds with high contents of a 3d transition metal, i.e., R Fe-2(14 - x) Co (x) B and RFe11 - x Co (x) Ti (where R = Y, Sm, 0 a parts per thousand currency sign x a parts per thousand currency sign 8), was studied. Alloys were prepared using high-purity rare-earth metals by two different methods: induction melting and argon-arc melting. Severe plastic deformation and rapid melt-quenching allowed preparation of nanostructured samples. Structural studies of the samples were performed by X-ray powder diffraction and atomic-force microscopy methods. Magnetic hysteretic properties were studied using a PPMS magnetometer in the temperature range of 4.2-300 K in fields to 20 kOe. It was shown that the dependences of fundamental magnetic parameters (Curie temperature, saturation magnetization, and magnetocrystalline anisotropy constant) on the cobalt content exhibit a similarity for both systems.
