The magnetic properties, structure defects of electrodeposited Fe-Ni-P alloys with various compositions and the thermostability at amorphous state have been studied by DSC, positron annihilation and electronic integrating instrument methods. The results show that the thermostability of amorphous Fe-Ni-P alloys increases with Fe content. Emergence and recrystallization of stable phases defer as the P content of the coating increases. The minimum Hc, Br and Ph occur at 9.4 P (wt pct) content. Maximum Hc, Br and Ph occur at the weight ratio of Fe to Ni equaling to 1/9.

By using an analytic expression of the effective dielectric function of the composite with a periodic geometry which we have derived by using the Fourier expansion technique, we calculated and discussed the frequency dependence of the effective dielectric function, and compared it with those prospected by the scale theory.
