Abstract:

The influence of rapid quenching from the melt on the magnetic and magnetothermal properties of the (Gd1-xTbx)(12)Co-7 samples has been investigated. The melt-spun (Gd1-xTbx)(12)Co-7 alloys are observed to exhibit a ferromagnetic-like behavior and increased T-C values at low Tb concentration in comparison with crystalline counterparts. The amorphization is suggested to result in the appearance of a small magnetic moment on Co atoms in Gd-rich liquid-quenched alloys. In low magnetic fields, the melt-spun (Gd1-xTbx)(12)Co-7 alloys with high Tb concentrations exhibit enhanced values of the isothermal entropy change and refrigerant capacity then the crystalline compounds of the same composition.
