Novel Magnetic Properties of Solid Helium‐3

FEB 01, 1987

At low densities solid helium exhibits two distinct magnetically ordered phases that are easily accessible with present technology; studies of these systems are enhancing our understanding of nuclear magnetism and atomic exchange in quantum solids.

Nuclear magnetic ordering in solid helium‐3 provides the ultralow‐temperature physicist with a unique opportunity to study cooperative magnetic phenomena in a quantum spin system. There are two known—and very different— magnetic phases of low‐density solid ${He}^{3},$ and at higher densities ferromagnetism may exist. with ordering temperatures at low densities near 1 mK, these systems are easily accessible with modern demagnetization cryostats. Over the next few years experimental and theoretical studies of these systems will advance considerably our understanding of nuclear magnetism.
