Abstract
The magnetic properties of the (001) surface of chromium at finite temperature are investigated by means of spin-fluctuation theory. It is found that, in contrast with the behavior in the bulk, large localized magnetic moments form at the surface. Interactions between these moments and their coupling to bulk spin fluctuations are included in the calculations. The results show that magnetic ordering at the surface persists well above the bulk Néel temperature. Comparison is made with available experimental results.
