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.

在这个项目中，我们研究如何磁畴和磁畴壁可以通过温度梯度控制。通过以ns激光脉冲的干涉图案的形式照射激光或通过聚焦的cw和fs激光，产生局部温度梯度，其引起磁畴配置的变化。通过比较不同照射方案的效果和模拟所得温度，将确定导致畴结构变化的机制。
