Abstract
Understanding the subtle link between coercivity and microstructure is essential for the development of higher performance magnets. In the case of R–Fe–B (R = rare earth) based materials this knowledge will be used to enable the development of high coercivity, Dy-free permanent magnets, which are relevant for clean energy technologies. A combination of high resolution characterization, molecular dynamics and micromagnetic simulations and model thick film systems has been used to gain valuable new insights into the coercivity mechanisms in R–Fe–B magnets.
