Nanocrystalline structure formation and magnetic hysteresis properties of Y-Fe-Co-B alloys
Popis výsledku v původním jazyce
In the present work a study of the influence of structural state on magnetic hysteresis properties of Y2(Fe1-xCox)14B compounds was carried out. Starting alloys were prepared by induction melting in an Ar atmosphere. Y-Fe-Co-B alloys with a nanograin structure were obtained by various techniques such as a severe plastic deformation (SPD) and by the classical melt spinning. Electron microscopy and X-ray analysis were used for the structural investigation. The magnetization measurements were performed using a SQUID magnetometer. It is shown that the relatively high values of coercive force are observed in such weakly-anisotropic alloys as Y2(Fe1-xCox)14B in case of achieved nano-grain structure. The effect of remanence enhancement is observed in rapidlyquenched Y2Fe14B alloys at T = 4.2 K. The influence of hydrogen on magnetic hysteresis properties is studied as well.
