| Abstract: | We have studied the one-magnon excitation in NiF2 crystals by the method of right-angle light scattering from 1 to 73°K. The temperature dependence of frequency and line width agrees very well with previous far infrared absorption data. The temperature dependence of the integrated intensity follows the theoretical prediction but deviates from the previous far infrared data. |
