摘要：

The temperature dependence of the magnetization for Fe88Zr7B4Cu1 amorphous alloy has been measured. M(T) has been fit using a Handrich-Kobe model with a modified Brillouin function with an additional exchange fluctuation term. Here for the first time, an asymmetrical distribution of the exchange interactions is proposed based on empirical knowledge of the Bethe-Slater curve. A two-parameter exchange fluctuation is shown to give significantly better fits to M( T) for these amorphous alloys. (C) 1999 American Institute of Physics. [S0021-8979(99)76608-9].
