Diffusion behavior and coercivity enhancement of Tb-containing NdFeB magnet by dip-coating TbH3

Diffusion behavior and coercivity enhancement of Tb-containing NdFeB magnet by dip-coating TbH3

There is a growing demand for high coercivity of NdFeB magnets with low heavy rare earth in the emerging applications. In this work, dip-coating 0.02 g and 0.09 g TbH3 on the Tb-containing NdFeB magnet enhance coercivity at room temperature，respectively. The highest coercivity achieve about 30 kOe a...
