- 論文の詳細を見る
The temperature dependence of the surface magnetization is calculated in the mean field approximation for the (1,0,0) surface of the face-centered-cubic (f.c.c.) crystal with the nearest and the next nearest neighbor exchange interactions. It is assumed that the spin magnitudes and exchange interactions are not changed near the surface. Based on the exact numerical calculations, the validity of the surface sheet model (SSM) is shown, where the spatial variation is assumed only between the surface and the second layers.
