Phys. Rev. Lett. 35, 1442–1444 (1975)Two-, Three-, and Four-Atom Exchange Effects in bcc 3HeReceived 22 September 1975; published in the issue dated 24 November 1975 We have made mean-field calculations with a Hamiltonian obtained from two-, three-, and four-atom exchange in bcc solid 3He. 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. © 1975 The American Physical Society URL:
