Nuclear Spin Ordering of Solid 3He in a Magnetic Field
The effect of an external magnetic field on the nuclear spin ordering in solid 3He has been observed for fields up to 1.2 T. For B ≲ 0.42 T the ordering is similar to the zero field transition reported by Halperin, et al. and the transition temperature is depressed by the field. In higher fields, however, the ordering region is broadened and moves to significantly higher temperatures with increasing fields.
