Abstract

We report on the magnetic properties, magnetocaloric effect (MCE) and critical exponents in amorphous Co100−xEr x (x = 55 and 65), prepared by liquid quenching technique. The transition temperature from ferromagnetic to paramagnetic state has been evaluated according to M(T) measurements, and it is found to be 26 and 15 K for Co45Er55 and Co35Er65, respectively. The magnetization dependence M(H, T) on the temperature T and magnetic field H was measured carefully in the critical region. Magnetic entropy change (– ΔS M ) allowing estimation of the MCE was determined based on thermodynamic Maxwell’s relation. The magnetocaloric study exposes a quite large value of the magnetic entropy change, which decreases when increasing Er concentration. For an applied magnetic field of 5 T,the values of (– ΔS Max) peak are about 10.8 and 9.8 J kg −1 K −1 for Co45Er55 and Co35Er65, respectively. From the field dependence of the magnetic entropy ΔS M (ΔS M α H n) and the relative cooling power (RCP) (RCP α H 1+1/δ), it was possible to evaluate the critical exponents of the magnetic phase transitions. Their values are in good agreement with those obtained from the critical exponents using a modified Arrott method.
