Abstract
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.Keywords
