Abstract

The magnetocaloric effect of a coordination polymeric material with a repeating unit of Gd(OH)CO3 has been studied experimentally using isothermal magnetization and heat capacity measurements. The maximum entropy change, −ΔSm, reaches 66.4 J kg−1 K−1 or 355 mJ cm−3 K−1 for ΔH = 7 T and T = 1.8 K. Density functional theory (DFT) calculations show weak and competing antiferromagnetic interactions between the metal centres.
