“…Parent et al [24], in 1987, prepared Mg-and Si-doped a-Fe 2 O 3 under a plasma spark and found the presence of Fe 3 O 4 in the samples. They concluded that the presence of Fe 3 O 4 in a-Fe 2 O 3 improved the photoresponse to a great extent.…”

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.
