Ultrafast dynamical path for the switching of a ferrimagnet after femtosecond heating
U. Atxitia, T. Ostler, J. Barker +3
Ultrafast laser-induced magnetic switching in rare earth, transition metal ferrimagnetic alloys has recently been reported to occur by ultrafast heating alone. Using atomistic simu…
The Landau-Lifshitz-Bloch equation for ferrimagnetic materials
U. Atxitia, P. Nieves, O. Chubykalo-Fesenko
We derive the Landau-Lifshitz-Bloch (LLB) equation for a two-component magnetic system valid up to the Curie temperature. As an example, we consider disordered GdFeCo ferrimagnet w…
Unified decoupling scheme for exchange and anisotropy contributions and temperature-dependent spectral properties of anisotropic spin systems
R. Bastardis, U. Atxitia, O. Chubykalo-Fesenko +1
We compute the temperature-dependent spin-wave spectrum and the magnetization for a spin system using the unified decoupling procedure for the high-order Green's functions for the…
