Magnetic and magnetocaloric properties of Gd2MoSi2C

Abstract

We investigate the intrinsic magnetic properties and magnetocaloric effect of Gd2MoSi2C by means of magnetization measurements in steady (14 T) and pulsed (56 T) magnetic fields, complemented by specific heat data. It is shown that the intermetallic compound Gd2MoSi2C exhibits an antiferromagnetic ground state below the Néel temperature TN = 19 K. The analysis of the disordered paramagnetic phase has led to a paramagnetic Curie temperature θP = -13 K and an effective magnetic moment μeff = 7.96 μB/Gd. At 2 K, the magnetization of Gd2MoSi2C reaches full saturation for an applied magnetic field of about 23 T; yielding a field-polarized or saturated phase with a mean magnetic moment of 7.02 μBGd. Of particular interest is the temperature dependence of the magnetic entropy change which passes through a minimum. Under an external field variation of μ0ΔH = 9, 7 and 3 T, the maximum isothermal entropy change ΔSM is found to be -4.98, -3.08 and -0.67 JKg-1K-1, respectively.
