Computing Magnetic Noise With Micro-Magneto-Mechanical Simulations

We study magnetic noise caused by the interaction of domain walls with defects. In the first step, we formulate a micro-magneto-mechanical material model using the generalized standard materials framework. We use this model in the subsequent step, in which we devise a scheme to compute magnetic noise based on ensemble averaging. We demonstrate our approach with numerical examples using the finite element method.
