Abstract
Orientational phase transitions are investigated within the Heisenberg mode l with single-site anisotropy. The temperature dependence of the cone angle is calculated analytically within the spin-wave theory. The role of the qu antum renormalizations of anisotropy constants is discussed. A comparison w ith the experimental data on the cone-plane orientational transition in hol mium is performed.
