Abstract
We have studied the magnetic properties of the frustrated triangular anti-ferromagnet Gd3Ga5O12 (GGG) by means of classical Monte Clarlo simulations. Low-temperature specific heat, magnetization, susceptibility. autocorrelation function and neutron scattering function have been calculated for several models including different types of magnetic interactions and with the presence of an external magnetic field. In order to reproduce the experimelltally observed properties of GGG, the simulation model must include nearest neighbor exchange interactions and also dipolar forces. In zero field there is a tendency to form incommensurate short-range magnetic order around positions in reciprocal space where antiferromagnetic Bragg peaks appear in an applied magnetic field.
