    "abstract": "The notion of spin squeezing involves reduction in the uncertainty of a\ncomponent of the spin vector below a certain limit. This aspect has been\nstudied earlier for pure and mixed states of definite spin. In this paper, this\nstudy has been extended to coupled spin states which do not possess sharp spin\nvalue. A general squeezing criterion has been obtained by requiring that a\ndirect product state for two spinors is not squeezed. The squeezing aspect of\nentangled states is studied in relation to their spin- spin correlations.",
