摘要

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.
