dc.description.abstractWe theoretically study the occurrence of magnetic friction of a nanometer-sized tip scanning a magnetic surface by studying the dynamics of a model of classical spins interacting through dipolar and exchange interactions, neglecting thermal effects. We find that for small scanning velocities, the friction force linearly scales with the velocity, with a slope proportional to the phenomenological damping parameter of the LandauLifshitz Gilbert equation. At higher velocities, the friction vs velocity relationship becomes rather complex with the presence of a maximum that is explained by the excitations of spin-wave resonances in the sample.eng
