摘要
Abstract The eight possible types of collinear magnetic structure are determined in the molecular field approximation with the help of Smart's and Bertaut's methods. The Heisenberg isotropic model with five nearest‐neighbour exchange integrals is used. The stability conditions are presented in terms of phase diagrams.
