Abstract
For the Ising ferromagnet with S = 3/2 and S = 2, the effects of the three-site four-spin interaction on the magnetization and the Curie temperature have been investigated with the use of three-spin model approximation. It has been shown that the effects are large for the Ising ferromagnet with large spin.
