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 40â¯K and a second-order ferromagnetic transition around Curie temperature of 11.5â¯K. Under ÎÎ (magnetic field change) of 0-5â¯T, the values of âÎSMmax (maximum magnetic entropy change) and RCP (relative cooling power) are 12.1â¯J/kgâ¯K and 342â¯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 nâ¯=â¯0.58â¯Â±â¯0.03.
