Abstract

Elastic and inelastic neutron scattering work on the cubic pyrochlore antiferromagnets Y₂Mo₂O₇, Tb₂Ti₂O₇, and Tb₂Mo₂O₇ is reviewed. These materials are characterized by antiferromagnetically coupled moments residing on a network of corner-sharing tetrahedra. Geometrical frustration manifests itself strongly in such systems in that two of them display a spin-glass-like transition in the apparent absence of chemical disorder, while the other remains paramagnetic to at least 0.1 K, despite developing antiferromagnetic short-range order at 50 K.
