Nuclear magnetic susceptibility of solid3He with4He impurities

The nuclear magnetic susceptibility of bcc solid³He with a small concentration of⁴He is calculated in the high-temperature approximation. The exchange Hamiltonian used for the system is that obtained from a Hubbard-like cell model developed in earlier work. A brief discussion is also given of our general approach to the study of the magnetic properties of impure solid³He as compared to other approaches to the problem.
