We investigate the magnetic properties of a range of low-dimensional ferromagnets using a combination of fi?rst-principles calculations and atomistic spin dynamics simulations. This approach allows us to evaluate the ground state and ?nite temperature properties of experimentally well characterized systems such as Co/Cu(111), Co/Cu(001), Fe/Cu(001) and Fe/W(110), for di?fferent thicknesses of the magnetic layer. We compare our calculated spin wave spectra with experimental data available in the literature, and ?nd a good quantitative agreement. We also predict magnon spectra for systems for which no experimental data exist at the moment, and estimate the role of temperature e?ects.
