Abstract:The Curie phase line T C (x) of the diamagnetically diluted ferromagnets Eu x Sr 1−x S and the Néel phase line T N (x) of the diamagnetically diluted antiferromagnets Eu x Sr 1−x Te are analysed empirically on the basis of a meanfield approximation. Experimental data for the transition temperatures are collected from neutron scattering, magnetic specific heat and susceptibility measurements. Neither phase line, T C (x) or T N (x), is proportional to the concentration x of the magnetic atoms. It is shown that t… 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.
