Abstract :
In this paper, we study the cellular structure of Sm(Co,Fe,Cu,Zr)/sub z/, magnets reduces the pinning field depending on the ratio between the cells and the intercellular phase linearly, depending on the cell size and the thickness of the intercellular phase using three-dimensional static and dynamic micromagnetic simulation and analytical models.
