Micromagnetic simulations of demagnetization curves for single-phase nanocrystalline PrFeB magnet
چکیده انگلیسی

The Gauss–Seidel projection method developed in [E. Weinan, X.P. Wang, SIAM J. Numer. Anal. 38 (2000) 1647–1665 and X.P. Wang, C.J. Garcia-Cervera, E. Weinan, J. Comp. Phys. 171 (2001) 357] is used to calculate the demagnetization curves for the single-phase nanocrystalline PrFeB magnet. It is observed that magnetic reversal for PrFeB magnet starts near the grain boundary where the angle between the external magnetic field and easy direction of the magnet can be as large as 90∘90∘. We also calculated the demagnetization curves, coercivity μ0Hcμ0Hc and remanence JrJr for different temperatures. The numerical results are consistent with the experimental observations.
