Developed at CCFE under EUROfusion Enabling Research grant, this Spin-lattice dynamics simulation software generalise molecular dynamics to the case of magnetic materials and can simulate dynamic evolution involving non-collinear fluctuations of magnetic moments and translational motion of atoms on a million atom scale. These simulations have been applied to a variety of systems, such as iron thin films, the treatment of self-diffusion in iron and dynamic magneto-caloric effects, and can provide key informations on the materials such as thermodynamics, superconductivity, phase transitions, thermal conductivity, and thermal expansion
