Abstract
We introduce the nonlinear spin-coherent state (SCS) via its ladder operato r formalism and propose a type of nonlinear SCS by the nonlinear time evolu tion of the SCS. By a new version of spectroscopic squeezing criteria we st udy the spin squeezing in both the SCS and the nonlinear SCS. The results s how that the SCS is not squeezed in the x, y and z directions, and the nonl inear SCS may be squeezed in the x and y directions.
