| Research Abstract |
Magnetic properties of pyrochlore fluorides with a transition metal and a nonmagnetic ion of cadmium or mercury, are examined. All compounds have antiferromagnetic interactions of about 100K, however, they remain paramagnetic down to about 10K. This indicates spin frustration has strong effects on these systems. In addition, most of these systems exhibit field-induced magnetic transitions, which suggests that antiferromagnetically coupled pyrochlore systems generally have field-induced magnetic transitions.
