The preparation and the magnetic properties of the hexagonal compounds MCr2X4 (M = Pb, Sr, Ba, Eu; X = S, Se) and MV2X4 (M = Sr, Eu; X = S, Se) are reported. SrV2S4 is Pauli‐paramagnetic, BaCr2S4 antiferromagnetic, while the other chromium compounds are ferrimagnetic; their magnetizations are small, except for the europium compounds EuCr2X4 (X = S, Se) where they reach appreciable values at low temperatures. Preliminary data on electrical and optical properties show that the chromium compounds are semiconducting, while SrV2S4 is metallic.
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.
