摘要：

The effect of Jahn-Teller phonons on the magnetic and orbital:structure of LaMnO3 is investigated using a combination of relaxation and Monte Carlo techniques on three-dimensional clusters of MnO6 octahedra. In the physically relevant region of parameter space for LaMnO3, and after including small corrections due to tilting effects, the A-type antiferromagnetic and C-type orbital structures were stabilized, in agreement with experiments.
