Control of magnetic domains and domain walls by thermal gradients (C11)

点击翻译按钮获取中文摘要

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.
