| Abstract: | Multiferroic behavior in an isotropic Heisenberg spin glass with Gaussian random fields, incorporated by magnetoelectric coupling derived from the Landau symmetry argument, are investigated. Electric dipole glass transitions at finite temperature, due to coupling, are demonstrated by Monte Carlo simulation. This electric dipole glass state is solely ascribed to the coupling term with chiral symmetry of the magnetization, while the term associated with the spatial derivative of the squared magnetization has no contribution. |
