Abstract
Abstract Large plate-like single crystals of La 5 Mo 4 O 16 were prepared by electrolyzing molten mixtures of La 2 O 3 , MoO 3 and Na 2 MoO 4 . The temperature dependence of electrical resistivity in the ab plane and parallel to the c-axis of the single crystal shows semiconducting behavior in the temperature range 180–300 K and a sharp upturn in the resistivity below ∼180 K. The temperature variation of the susceptibility in the temperature range 200–300 K follows Curie-Weiss behavior with an observed moment ∼1.66 B.M. corresponding to one localized electron per formula unit. The magnetization study on a batch of randomly oriented single crystals showed a sharp decrease in the susceptibility at ∼180 K indicative of a long-range antiferromagnetic order. Directional magnetization studies on La 5 Mo 4 O 16 indicated that the magnetic ordering is confined to the ab plane. The anomalous electrical and magnetic properties are discussed in terms of the unique structure of La 5 Mo 4 O 16 .
