Structure and Magnetocaloric Properties of Two Cadmium Gadolinium Borates
Two cadmium-gadolinium-borates, CdGdB<sub>5</sub>O<sub>10</sub> and Cd<sub>4</sub>GdB<sub>3</sub>O<sub>10</sub>, were synthesized as polycrystalline samples, and their single crystals were also grown. Monoclinic structures in space groups <i>P</i>2<sub>1</sub>/<i>n</i> and <i>Cm</i> were identified for the two compounds, with magnetic properties characterized through M-T and M-H measurements. The maximum magnetic entropy change (-Δ<i>S</i><sub>M</sub><sup>max</sup>) of CdGdB<sub>5</sub>O<sub>10</sub> reaches 23.94 J·kg<sup>-1</sup>·K<sup>-1</sup> at 5 T and 3 K, approaching the value reported for commercial Gd<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> under identical conditions. Cd<sub>4</sub>GdB<sub>3</sub>O<sub>10</sub> exhibits a -Δ<i>S</i><sub>M</sub><sup>max</sup> of 13.96 J·kg<sup>-1</sup>·K<sup>-1</sup> at 5 T and 2 K, comparable to Dy<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub>. These two cadmium-gadolinium-borates may have potential for cryogenic magnetic cooling applications due to their high -Δ<i>S</i><sub>M</sub><sup>max</sup>, broad entropy plateau, and stable structure. Additionally, the optical and thermal properties of CdGdB<sub>5</sub>O<sub>10</sub> were investigated.
