Abstract:Results of magnetic and ESR investigations are given of Sm,(Mnl -zFez)23 compounds for 0 < x < < 0.55, above the magnetic ordering temperature Tc. Significant deviations from the Curie-Weiss law are found and also a strong field-dependence of the magnetic susceptibility in a wide temperature range above Tc. ESR investigations performed in the X-band in the temperature range from 150 to 400 K show an increase of the ESR signal with the increase of Fe concentration in the compound and also anomalous temperature… 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.
