Magnetic Susceptibility of Quasi-two-dimensional Cuprate Antiferromagnets
2013
Journal of Research in Physics
Parallel magnetic susceptibility temperature dependence of the high-TC superconducting parent compound La2CuO4 is calculated in both antiferromagnetic (AFM) and paramagnetic phase. By making use of the quantum Heisenberg three-dimensional AFM model including the in-plane spin anisotropy, the calculation is performed within the framework of three different theories: Green's function theory in random-phase approximation (RPA), linear spinwave (LSW) theory and mean-field (MF) theory. The results
