Phys. 97, 084109 (2005); 10.1063/1.1861517 Thermogravimetric measurements of thin iron films magnetization near their Curie temperature III situ temperature dependent magneto-optic Kerr effect measurements in ultrahigh vacuum are presented for 80 and 300 A thick Gd(0001) films. Films were deposited at 300 K and stepwise annealed to 820 K It was found that the remanent magnetization M,(T) depends on the annealing temperature. The as-deposited films have a reduced Curie temperature T, , e.g., T,(SO A)=273 K, which gradually shifts up to the bulk T, of Gd upon annealing. The change.s in &f,(T) are correlated with a sharpening of the Gd low energy electron diffraction pattern. The best magnetic homogeneity and structural coherence is found for films annealed to 620 K. At higher temperatures the films break up into large three-dimensional islands with nearly uncovered W areas in between (W Auger is observed). The magnetic behavior was simulated with a model which assumes a Gaussian distribution of T,. values. From these simulations and the known bulk pressure dependence of Ti we estimate the mean strain and the strain distribution within the films.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
