Abstract

Amorphous Co₃₅Er₆₅ ribbon was synthesized using melt spinning technique. Their magnetic properties and magnetocaloric effect (MCE) have been studied by the magnetization and isothermal magnetization of different temperature measurements. It is found that the sample obeys to the first-order magnetic transition (FOMT) from ferromagnetic (FM) to paramagnetic (PM) state at the Curie temperatures T_c=10 K. Using the thermodynamic Maxwell's relation, magnetic entropy change (-ΔS_M) is estimated and discussed in terms of MCE. The ribbon presents a large magnetocaloric effect at low temperature reaching 5.97 J/K kg under magnetic field of 0-5 T.
