Transitions of complex spin spiral magnetic structure in FeGe2 nanowires based on the magnetism comparison with FeGe2 films and unique transport properties
Abstract:Iron germanium nanowires and films were prepared via a high pressure catalyst free chemical vapor deposition on Ge(111) wafer. Both nanowires and films were identified to be FeGe2. However, nanowires exhibited a saturation in field dependent magnetization while that of film did not. Magnetic field dependent resistivity showed two drops in warming curve from 10-300K with a magnetic field of 6T and 9T. These abnormal drops might attribute to a less scattering of electrons from complex spiral structures. Temperat… 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.
