摘要：
The temperature dependence of Rayleigh waves in Fe(110), measured by helium atom scattering in the range of 150 to 905 K (0.91 T(c)), is shown to provide new information on surface magnetization. The magnetic shifts of the surface phonon frequencies exhibit a large anisotropy, with the [110BAR] direction showing the expected decrease of frequency for increasing temperature, while the [001] direction shows an anomalous increase with temperature. The results are interpreted in terms of a simple model.
