The magnetocaloric effect in samples of the Gd2In compound was studied using the direct method. Both inverse and direct magnetocaloric effects were observed at different temperatures and magnetic fields. The temperature dependence of a first-order metamagnetic phase transition was found to exhibit kinetic arrest.
The magnetocaloric effect (MCE) in samples of the Gd2In compound has been studied by the direct method in temperature range of 4-240 K in magnetic fields of Bitter coil up to 14 T. The maximum detected value of the inverse MCE at cryogenic temperatures in the 1st-order metamagnetic phase transition (PT) is Delta T-ad = - 0.5 K at T-0 =45 K in the field of 1.8 T. The MCE in this temperature range changes sign with increasing of the magnetic field up to 5 T, and the direct MCE is observed with further increasing of the field. The kinetic arrest of the 1st-order metamagnetic PT is observed on the temperature dependence of magnetization in the steady magnetic field of 5 T. The direct MCE in the Curie temperature Tc = 200 K increases with increasing of the magnetic field, and the effect maximum shifts to higher temperatures. The maximum detected value of the direct MCE is Delta T-ad =7.8 K at T-0 =215 K in the field of 14 T.
