Abstract: Magnetocaloric effect (MCE) and thermal conductivity of two gadolinium hydroxides, Gd(OH)<subscript>3</subscript> (1) and Gd<subscript>2</subscript>O(OH)<subscript>4</subscript>(H<subscript>2</subscript>O)<subscript>2</subscript> (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<superscript>−1</superscript> K<superscript>−1</superscript> and 59.09 J kg<superscript>−1</superscript> K<superscript>−1</superscript>, respectively. Investigation of their thermal conductivity reveals that the thermal conductivity for 1 is significantly better than that for 2. [ABSTRACT FROM AUTHOR]
