Using the Landau-Lifshitz-Bloch (LLB) equation for ferromagnetic materials,we derive analytic expressions for temperature dependent absorption spectra asprobed by ferromagnetic resonance (FMR). By analysing the resultingexpressions, we can predict the variation of the resonance frequency anddamping with temperature and coupling to the thermal bath. We base ourcalculations on the technologically relevant L1$_0$ FePt, parameterised fromatomistic spin dynamics simulations, with the Hamiltonian mapped from ab-initioparameters. By constructing a multi-macrospin model based on the LLB equationand exploiting GPU acceleration we extend the study to investigate the effectson the damping and resonance frequency in ${\mu}$m sized structures.
