Gd(0001): A Semi-Infinite Three-Dimensional Heisenberg Ferromagnet With Ordinary Surface Transition

Published

Abstract

By comparing the surface and bulk magnetizaiton of smooth, well-ordered Gd samples, we show that the surface has an ordinary transition, I.e. a common curie temperature for surface and bulk. A quantitative statistical analysis of the temperature dependent magnetization is presented. Critical exponents for both surface, Βs = 0.83 1 0.04, and bulk, ΒB = 0.376 1 0.015, are consistent with the semi-infinite Three-Dimensional Heisenberg model with homogeneous exchange.
