Interactions between magnetic skyrmions — •László Udvardi1,2 and Mátyás Török1 — 1Budapest University of Technology and Economics, Budapest Hungary — 2MTA-BME Condensed Matter Research Group, Budapest, Hungary
Recently magnetic skyrmions received considerable attention due to their potential in spintronic devices. Magnetic properties of skyrmions are often described by a classical Heisenberg model with tensorial couplings. We have developed a conjugate gradient method to find the local minima of the energy of a classical spin system. By analyzing the energy of an isolated skyrmion and of pair of skyrmions in the case of FePd bilayer on Ir(111) substrate1 interactions can be derived as a function of the separation of the skyrmions. The knowledge of the pair interactions permits us to perform Monte Carlo simulations treating skyrmions as quasi particles.
