Pseudogap Behavior of Dynamical Properties of High-T_c Cuprates

Abstract

Dynamical properties of 2D antiferromagnets with hole dopingare investigated to elucidate the effects of short-range local magnetic orderon the temperature dependence of the dynamical magnetic susceptibility.We show the pseudogap-like behavior of the temperature dependence ofthe NMR relaxation rate. We also discuss the implications of the results inrelation to the observed spin-gap-like behavior of low-doped copperoxide high-T_c superconductors.
