- Аннотация: Magnetic ordering and magnetocaloric effect of polycrystalline Ce3Ni6Si2-type Gd3Ni6Ga2 (space group Im-3m, N 229, cI44) has been investigated via heat capacity and magnetic measurements. Gd3Ni6Ga2 exhibits ferromagnetic ordering at TC = 104 K and a field-sensitive transformation of magnetic ordering at Tm = 38 K. At 2 K, it is soft ferromagnetic with magnetic moment per Gd of 6.73 mB in 90 kOe. Heat capacity measurements in zero magnetic field indicated the Debye temperature around 320 K and peak in heat capacity around TC, only. Gd3Ni6Ga2 shows table-like magnetic entropy change of -4.9 J/kg*K at TC and -3.8 J/kg*K at Tm in a field change of 50 kOe with a wide working temperature range.
