稀土永磁及磁记录材料的矫顽力与有效激活体积

Coercive Force and Effective Activation Volume in Rare Earth Permanent Magnets and Magnetic Recording Materials

指出了文献 [1]中的一个错误。给出了不同模型的稀土永磁材料以及磁记录材料的矫顽力 Hc和有效激活体积υ之间的正确关系 ,这样的关系被表示成一个复杂的函数关系 ,同时指出 ,对不同模型的稀土磁性材料 。

Author pointed out a mistake in the preceding article [1] The correct relationships between H c and υ were deduced for the different models of rare earth permanent magnets and magnetic recording materials, which can be written as a complex function But it has different forms for the different models of rare earth permanent magnets
