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

在该项目中，我们研究了如何通过温度梯度来控制磁畴和磁畴壁。通过以ns激光脉冲干涉图样的形式照射激光，或者通过聚焦的CW和FS激光来产生局部温度梯度，从而引起磁畴结构的变化。通过比较不同照明方案的效果和对结果温度的模拟，应确定导致磁畴结构变化的机制。

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.
