Title: Magnetic critical properties of the undoped cuprates in a quasi-two-dimensional nonlinear-sigma-model approach

Abstract

A quasi-two-dimensional (2D) nonlinear sigma model (NLSM) is used to model the antiferromagnetism of the insulating layered undoped cuprate materials. As Chakravarty, Halperin, and Nelson (CHN) did for their 2D NLSM, we make a renormalization-group analysis of the quasi-2D NLSM. In contrast with CHN's 2D model, the quasi-2D NLSM yields a nonzero Neel temperature so that our theoretical Neel temperatures can be fitted completely with the experimental ones. Our theoretical correlation lengths are fitted very well with the experimental La{sub 2}CuO{sub 4} data of the materials within 220 K above {ital T}{sub {ital N}}.
