Abstract
The glass forming ability, magnetism and magneto-caloric effect have been investigated in Er60Ni30Co10 melt-spun alloy by using X-ray diffraction, differential scanning calorimetry and magnetization measurements. The amorphousized Er60Ni30Co10 exhibits a relatively wide supercooled liquid region of 40 K and a second-order ferromagnetic transition around Curie temperature of 11.5 K. Under ΔΗ (magnetic field change) of 0–5 T, the values of −ΔSMmax (maximum magnetic entropy change) and RCP (relative cooling power) are 12.1 J/kg K and 342 J/kg, respectively. Furthermore, the field dependence of the magnetic entropy change for Er60Ni30Co10 obeys the phenomenological universal curve and corresponds to a field independent exponent of n = 0.58 ± 0.03.
