Abstract

For pt.I see ibid., vol.8, no.16, p.2642 (1975). The spin-1/2 XY model with annealed site impurities is studied on the three cubic Bravais lattices. The model is equivalent to the Takagi model of 3He-4He mixtures (1972). Series are generated in magnetic-site fugacity z and magnetic ion concentration nm to degree seven. The phase transition curve is estimated for all three lattices in the Tnm plane and for the FCC lattice in the Tz plane. Also an estimate of the lambda line for n3+n4=0.65 is made in the TX3 plane. The tricritical point is approximately located.
