Critical analysis of a reported anomalous low-temperature susceptibility of solid 3He at high molar volume.

Abstract

The observation of an anomalous magnetic susceptibility of solid $^{3}\mathrm{He}$ for bcc samples of large molar volume was a new challenge for the understanding of the solid phase. We review the experimental facts, comment on their interpretation, and show that the melting of the sample should be considered as a possible explanation of the anomaly.
