Zusammenfassung

Bloch points in permalloy cylinders are investigated using a micromagnetic framework, where thermal effects are included via the Landau-Lifshitz-Bloch equation of motion. We show that this enables micromagnetic modeling of a Bloch point avoiding the problem of singularities, which have been reported in the literature so far. The details of the Bloch point which we reveal are compared with earlier analytic approximations describing its geometry and the magnetization drop in its center. The temperature dependence of characteristic parameters, like the Bloch point radius or the azimuthal inflow angle is given in the full temperature range.
