The Mossbauer spectra were obtained by using a Mossbauer spectrometer within the temperature range from liquid-nitrogen temperature to 650 Ii. From the temperature dependence of the natural logarithmic absorption area of tire Mossbauer spectrum, the Debye temperature were determined to be 277.198 K (sextet) and 183.847 K (central single line) for gamma -Ni-55Fe, and 289.043 K (sextet) and 211.127 K (central single line) for gamma -Ni-45Fe. The strength of the interaction between magnetic ions and the coefficients of the spin-wave for the samples were also determined by applying the spin-wave theory to the temperature dependence of the magnetic hyperfine field of the samples.
