Description of collective magnetization processes with machine learning models

Alexander Kornell, Lukas Exl, Leoni Breth +11

This work introduces a latent space method to calculate the demagnetization reversal process of multigrain permanent magnets. The algorithm consists of two deep learning models bas…

Exploring the hysteresis properties of nanocrystalline permanent magnets using deep learning

Alexander Kovacs, Lukas Exl, Alexander Kornell +11

We demonstrate the use of model order reduction and neural networks for estimating the hysteresis properties of nanocrystalline permanent magnets from microstructure. With a data-d…

Full-Spin-Wave-Scaled Finite Element Stochastic Micromagnetism: Mesh-Independent FUSSS LLG Simulations of Ferromagnetic Resonance and Reversal

Harald Oezelt, Luman Qu, Alexander Kovacs +11

In this paper, we address the problem that standard stochastic Landau-Lifshitz-Gilbert (sLLG) simulations typically produce results that show unphysical mesh-size dependence. The r…

Conditional physics informed neural networks

Alexander Kovacs, Lukas Exl, Alexander Kornell +11

We introduce conditional PINNs (physics informed neural networks) for estimating the solution of classes of eigenvalue problems. The concept of PINNs is expanded to learn not only…

Effect of grain-boundary diffusion process on the geometry of the grain microstructure of NdFeB nanocrystalline magnets

Ivan Titov, Massimiliano Barbieri, Philipp Bender +6

Hot-deformed anisotropic NdFeB nanocrystalline magnets have been subjected to the grain-boundary diffusion process (GBDP) using a eutectic…
