MAGNETOCRYSTALLINE ANISOTROPY CONSTANTS, ROTATIONAL HYSTERESIS ENERGYAND MAGNETIC DOMAIN-STRUCTURE IN UFE6AL6, UFE9ALSI2 AND SCFE10SI2 INTERMETALLIC COMPOUNDS

The magnetic torque, T, was applied to determine the anisotropy consta nts K-1 and K-2 of the UFe6Al6, UFe9AlSi2 and ScFe10Si2 compounds. The mechanism of magnetization reversal processes in these compounds was investigated on the basis of the analysis of the rotational hysteresis energy, W-r and rotational hysteresis integral, R, calculated from th e magnetic torque curves. Applying the powder pattern method, magnetic domain structures were observed. Moreover, the fundamental parameters of the domain structure were determined.
