Abstract

Magnetic refrigeration technology is one of the important technologies to realize sub-Kelvin temperature environment, in which magnetocaloric materials are of great importance. Polycrystalline powder of β’-Gd₂(MoO₄)₃ was prepared by solid-phase synthesis, and the structure as well as magnetic properties were further investigated. The thermomagnetic curves show that the magnetic ordering temperature is about 0.6 K for β’-Gd₂(MoO₄)₃. The maximum magnetic entropy change of β’-Gd₂(MoO₄)₃ was calculated to be 20.7 and 34.1J kg⁻¹·K⁻¹ under the magnetic field changes from 0 to 1 T and 2 T, respectively. Moreover, the magnetic entropy change curves of β’-Gd₂(MoO₄)₃ at low field have obvious platform-like characteristic, which allows it to act as a refrigerant for wide refrigeration temperature range, thereby improving the overall heat transfer efficiency of the system. These properties make β’-Gd₂(MoO₄)₃ a powerful candidate of magnetic refrigeration materials in the sub-Kelvin temperature cooling.
