The temperature dependence of the magnetization and quadrupole order parameters of the Blume–Emery–Griffiths (BEG … solutions, metastable and unstable solutions of the order parameters are found for various values of the two different coupling … parameters, α=J/K and γ=D/K. These solutions are classified using the free energy surfaces in the form of a contour map. The …
