In the project we study how magnetic domains and domain walls can be controlled by temperature gradients. By illumination of laser light in form of an interference pattern of a ns-laser pulse or by focused cw- and fs-laser local temperature gradients are created which induce changes in the magnetic domain configuration. By comparison of the effect of different illumination schemes and simulations of the resulting temperatures the mechanisms leading to changes in the domain structure shall be identified.

MFM microscopy of magnetic stripes which were prepared by pulsed laser lithography at periods of 1 µm and 650 nm. Dark and bright colors correspond to magnetization pointing out-of-plane in different directions.
