• The heat capacities of Gd(2)Zr(2)O(7) and Gd(2)Hf(2)O(7) both show sharp peaks in the vicinity of 0.77 K, consistent with the existence of long range magnetic order. They are superimposed in both cases on broader maxima centered at approximately 1 K, presumably due to short range spin correlations. Both compounds exhibit antiferromagnetic interactions, with Weiss constants of approximately -7 K. Comparisons are made to earlier results for the isomorphic compounds Gd(2)Ti(2)O(7) and Gd(2)Sn(2)O(7).
