Abstract:A study is made of the effect of annealing on the structure of permalloy polycrystalline thin films. Thin films of 85% Ni-15y0 Fe are investigated using an electron microscope at high temperatures. The results show that annealing causes the growth of irregularities in the thin film surface. I n extreme cases this may invalidate the concept of a uniform thin film thickness. The growth of crystallites is not isotropic but occurs most vigorously in the surface of the thin film.Der EinfluB einer Temperung auf die … Show more
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.
