Abstract

We have made mean-field calculations with a Hamiltonian obtained from two-, three-, and four-atom exchange in bcc solid

{}^{3}{He}

. We are able to fit the high-temperature experiments as well as the phase diagram of Kummer et al. at low temperatures. We find two kinds of antiferromagnetic phases as suggested by Kummer's experiments.
