摘要：

We study the properties of the striped phases that have been proposed for the doped cuprate planar quantum antiferromagnets. We invoke an effective, spatially anisotropic, nonlinear sigma model in two space dimensions. Out theoretical predictions are in quantitative agreement with recent experiments. We focus on (i) the staggered magnetization at T = 0 and (ii) the Neel temperature as functions of doping; these have been measured recently in La2-xSrxCuO4 with 0 less than or equal to x less than or equal to 0.018. Good agreement with experiment is obtained using parameters determined previously and independently for this system. These results support the proposal that the low doping (antiferromagnetic) phase of the cuprates has a striped configuration.
