N2 - The adiabatic demagnetization refrigeration which is based on the magnetocaloric effect (MCE) of magnetic materials is an effective technology to attain sub-Kelvin temperature. In this paper, we report the magnetocaloric property of Gd-based borosilicate Gd3BSi2O10. It experiences a second-order magnetic phase transition at test temperatures range. Owing to the high Gd3+ ion / anion ligand ratio and weak magnetic interaction, Gd3BSi2O10 exhibits a large magnetic entropy change of 59.1 J·kg−1·K−1 at 2.6 K for Δμ0H = 7 T, which is comparable to that of the top-ranked refrigerants operating in the cryogenic range. Besides, Gd3BSi2O10 compound exhibits considerable relative cooling power of 543.7 J·kg−1 for Δμ0H = 7 T. These properties demonstrate that Gd3BSi2O10 is a promising magnetic refrigeration material.
