摘要：

Gd3Ga5O12 is strongly frustrated, possessing a Curie-Weiss temperature of - 2.3 K, while not ordering down to 25 mK, in zero field. Specific-heat and thermal-expansion measurements were made as a function of temperature (0-2 K) and magnetic field (0-2 T). The unusual phase diagram of this material, reported in the susceptibility measurements of Hov, Bratsberg, and Skjeltorp [J. Magn. Magn. Mater. 15-18, 455 (1980)], is verified by the present thermal behavior.
