Abstract
- Magnetic refrigeration technology based on Gd‐based paramagnets is expected to be applied to refrigeration in extremely low temperatures, thereby reducing the consumption of liquid helium. Here, we obtained a compound, Gd3TeBO9 with high Gd3+ concentration through element substitution. The Gd3+ concentration in this compound is as high as 2.4×1024 ions/kg, which is 33 % higher than the commercial Gd3Ga5O12 (GGG), and further magnetic tests show that Gd3TeBO9 has a large magnetic entropy change (57.44 J/(kg K) and 408 mJ/(cm3 K) at 2.6 K and 7 T), which is 1.5 times that of GGG, implying the possibility of its further development as an potential magnetocaloric material.
