摘要：

We measured the low-temperature ac magnetic susceptibilities ( , , and 3), static magnetization, and the specific heat of a high-quality single crystal of gadolinium gallium garnet (GGG), which is a geometrically frustrated Heisenberg magnet. We find a spin glass transition at low temperatures, in addition to unusual behavior in and 3. Comparison to nonmagnetic isomorphs and the low levels of structural and chemical disorder in GGG suggests that the transition is due to the highly frustrated geometry of the magnetic lattice. © 1995 The American Physical Society.
