Magnetic Noise of Magnetoelectric Sensors (A10)

本项目旨在了解和量化几何和物理缺陷以及连接的磁微观结构对磁电传感器磁噪声的影响。为此，我们使用专用的实验方法，如时间分辨原位磁域响应分析和局部噪声测量，这些方法将与高分辨和自适应微磁力学模拟相结合，包括自适应离散化方法和尺度转换方法。从发展的基本认识出发，我们将得出有针对性的降噪策略，并确定可行性限制。

The aim of this project is to comprehend and quantify the influence of geometrical and physical imperfections as well as the connected magnetic microstructure on the magnetic noise of magnetoelectric sensors. For this we use dedicated experimental methods, like time-resolved in-situ magnetic domain response analysis and local noise measurements that will be combined with high-resolved and adaptive micromagnetomechanical simulations including adaptive discretization approaches and scale transition methods. From the developed fundamental understanding, we will derive targeted strategies for noise reduction as well as identify feasibility limits.
