摘要 1 Introduction The R<sub>2</sub>Fe<sub>14</sub>B type compound (R=rare earths)is an important kind of magnetic materials. One of its important features is that it has very strong magneto-crystalline anisotropy,which exhibits very complex characteristics with different rare earth elements. The calculations of the magneto-crystalline anisotropy for compounds Nd<sub>2</sub>Fe<sub>14</sub>B and Pr<sub>2</sub>Fe<sub>14</sub>B have been made by many researchers using point charge model, but their results
