Competition of Spin and Charge Orders in a Model Cuprate
- 68 Downloads
We present results of the mean-field analysis of the competition between charge and spin orders in a model cuprate. Phase diagrams and temperature dependencies of the charge and magnetic order parameters are calculated for different doping given different values of the on-site correlation parameter, inter-site density-density coupling, and Heisenberg spin exchange integral.
