A magnetic hyperfine field induced at Ag sites near the interface between a Ag(100) crystal and an epitaxially grown bcc Fe(100) film has been measured with monolayer resolution. Utilizing perturbedangular-correlation spectroscopy with 111 In probes a magnetic hyperfine field in the first atomic Ag layer is found to be strongly reduced relative to the Fe bulk value and decreases very quickly as a function of distance from the interface. For both sides of the interface the temperature dependence is well described by a T 3͞2 spin-wave behavior; however, it is strongly enhanced on the nonmagnetic side.[S0031-9007(97)04342-1]
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.
