摘　　要：1 Introduction The R₂Fe₁₄B 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 Nd₂Fe₁₄B and Pr₂Fe₁₄B have been made by many researchers using point charge model, but their results
