Abstract

Magnetocaloric effect (MCE) and thermal conductivity of two gadolinium hydroxides, Gd(OH)3 (1) and Gd2O(OH)4(H2O)2 (2), are investigated. Magnetic studies indicate that both 1 and 2 exhibit antiferromagnetic interaction, and the MCE values for 1 and 2 at 2 K and ΔH = 7 T are 62.00 J kg?1 K?1 and 59.09 J kg?1 K?1, respectively. Investigation of their thermal conductivity reveals that the thermal conductivity for 1 is significantly better than that for 2.
