Anisotropic exchange in Nd–Fe–B permanent magnets
The exchange is critical for designing high-performance Nd–Fe–B permanent magnets. Here we demonstrate through multiscale simulations that the exchange in Nd–Fe–B magnets, including bulk exchange stiffness (Ae) in Nd2Fe14B phase and interface exchange coupling strength ( $J_{\rm int} $) between Nd2F...
