The Magnetic Behavior of the t-J Model

Abstract

Using the spin-hole coherent state representation, and taking the long range antiferromagnetic Néel order as the background of the spin degree part, we have studied the magnetic behavior of the t-J model in the usual slave boson and slave fermion treatment of the single occupation constraint, and shown that we can qualitatively explain the anomalous magnetic and transport properties of the normal state of the cuprate superconducting materials by the t-J model.
