    "abstract": "We introduce the nonlinear spin coherent state via its ladder operator\nformalism and propose a type of nonlinear spin coherent state by the nonlinear\ntime evolution of spin coherent states. By a new version of spectroscopic\nsqueezing criteria we study the spin squeezing in both the spin coherent state\nand nonlinear spin coherent state. The results show that the spin coherent\nstate is not squeezed in the x, y, and z directions, and the nonlinear spin\ncoherent state may be squeezed in the x and y directions.",
