| Fig.12 Micromagnetic simulation model of GBD heterogeneous behavior and grain structure (a), and magnetization distributions of T1 + B1 (b) and L1 + R1 (c) (To study the effect of diffusion direction, the diffusions from the top surface (pole surface), the bottom surface (pole surface), the left side surface, and the right side surface of the magnets are labelled as T, B, L, and R, respectively. To investigate the effect of diffusion depth, numbers 1, 2, and 3 are used to describe that two, three, and four layers of grains are changed to the core-shell structure, respectively; GBP—grain boundary phase)[ |
