Anomalous Low-Temperature Susceptibility of SolidHe3at High Molar Volumes

Abstract
The contribution to the low-temperature magnetic susceptibility of a small number of vacancies in bcc He3 is analyzed with recent NMR data used to estimate the vacancy contribution. It is shown that the susceptibility anomaly at very high molar volumes near the melting curve can be attributed to the polaron effect of a very small concentration of vacancies.
