The photon-added spin coherent state as a new kind of coherent state has been defined by iterated actions of the proper raising operator on the ordinary spin coherent state.In this paper,the quantum statistical properties of photon-added spin coherent states such as photon number distribution,second-order correlation function and Wigner function are studied.It is found that the Wigner function shows the negativity in some regions and the second-order correlation function is less than unity.Therefore,the photon-added spin coherent state is a nonclassical state.
