    摘要: Within the t–J model, the spin response of the doped triangular antiferromagnet in the underdoped and optimally doped regimes is studied based on the fermion-spin theory. The spinon part is treated by using the loop expansion to the second order. It is shown that although the dynamical spin structure factor and susceptibility exhibit the anomalous behaviors at the antiferromagnetic zone center, the particularly universal behaviors of the integrated dynamical spin structure factor and susceptibility present in the doped square antiferromagnet, are absent in the doped triangular antiferromagnet.
