Abstract:The magnetic susceptibility χ of single-crystal antiferromagnet FeGe2 (TN = 289 K) was measured in the temperature range from 4.2 to 300 K in a magnetic field H up to 40 kOe applied along the main crystallographic axes. For the antiferromagnetic (AFM) state at low temperatures, a strong increase in χ is observed with increasing H applied along the [100] axis, which reaches saturation at H≥H0∼ 11 kOe. It is assumed that this behavior is associated with a field-induced change in the AFM domain structure, and the… 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.
