Abstract

AbstractPump and probe techniques with ultrafast laser pulses represent a well established tool for the measurements of electron‐electron and electron‐phonon thermalization processes. It is shown that expanding these techniques to magnetic systems for spin‐lattice relaxation measurements requires a careful selection of the thermal characteristics of the samples. More precisely, a simulation of the thermal behavior of thin metal films heated by short laser pulses shows that film thickness and substrate thermal properties are crucial parameters.
