The Blume–Capel model is a <spin model> with $\sigma_i\in\{-1,0,1\}$ and Hamiltonian
$$
H=-J\sum_{\langle i,j\rangle}\sigma_i\sigma_j+D\sum_i\sigma_i^2-h\sum_i\sigma_i.
$$
Competition between the <Ising model>[Ising interaction] and the single-ion anisotropy $D$ produces a <tricritical point> in its phase diagram.

= Spin-1 Ising model
