Ising Ferromagnet with Biquadratic Exchange Interaction and Uniaxial Anisotropy

For Ising ferromagnets with S = 1, S = 3/2, and S = 2, the magnetization 〈Sz〉 and the Curie temperature TC are calculatded with the use of pair mode lapproximation. Assuming the bilinear and biquadratic exchange interactions (J and J′) between nearest‐neighbouring pair of spins and the uniaxial sing...
