A Heisenberg ferromagnet is considered in which the eigenvalues of S<sup>z</sup> and (S<sup>z</sup>)<sup>2</sup> are 1, 0, - lambda and 1, 0, lambda <sup>2</sup> where lambda is the asymmetry parameter lying between 0 and 1. It is shown that in this system a quadrupolar phase appears as an intermediate phase even when the ground state is ferromagnetic. The temperature T<sub>q</sub> at which the transition from the ferromagnetic to the quadrupolar phase occurs is derived with a molecular-field approximation. Two limiting cases lambda to 0 and lambda to 1 are also examined. |
