Paper Abstract

We apply high resolution x-ray diffraction to study the development of the c(2 X 2) phase of Pb on Ni(001). We observe lineshapes in agreement with the scaling theory of Ohta, Jasnow, and Kawasaki, but with an anomalously slow time dependence of average domain size R on time t, R (alpha) t0.12. The presence of 1% - 3% carbon on the surface apparently acts as a weak random field. We are able to understand the observed power law dependence and the observed effect of C density in an adaptation of the analysis of the random field Ising model given by Grinstein and Fernandez.
