Spin lattice dynamics (SLD) modeling is an approach to modeling magnetic interactions at the nanoscale. Current spin lattice dynamics models do not model magnetoelastic effects well, giving non-physical lattice parameters and poorly modeling behavior like forced volume magnetostriction. A new model, based on a temperature dependent offset that subtracts out the part of the magnetic interactions accounted for in the lattice potential to avoid double counting of forces, has been developed to address these shortcomings. The current model matches lattice parameter for no field applied conditions. Currently, forced volume magnetostriction is being studied with the model.
