Abstract

High-field magnetization measurements on BaVS<SUB>3</SUB> revealed a metamagnetic transition at <I>B</I><<I>B</I><SUB>M</SUB>\\simeq50 T to a newly identified field-induced ferromagnetic phase, which bears the magnetic moment of ∼0.4 μ<SUB>B</SUB>/V, approximately half of the saturation magnetization expected for <I>S</I>=1⁄2. The transition is associated with an essential change in the electronic state to a <I>poor</I> conductor, where the gapped <I>A</I><SUB>1<I>g</I></SUB> band remains open and only the poor conductivity of nearly localized <I>E<SUB>g</SUB></I> electrons is recovered by the field. Based on the magnetization results, a field-temperature phase diagram is proposed for BaVS<SUB>3</SUB>.
