Plasticity induced magnetisation losses in energy conversion processes
Application: Electro-mechanical energy conversions processes related to electromobility and conventional energy generation/conversion
Problem: Cutting of metallic sheets causes defects, which enhance magnetisation hysteresis and energy conversion losses.
Approach: Atomistic simulations of magnetic domain dynamics in a lattice with defects (dislocation and interface)
Goal: Identify mechanisms of loses to develop mechanism-based materials design approach to increase conversion efficiency
