Abstract
The compound CsScUSe3(Se2) has been synthesized by the reaction of U, Sc, and Se in a CsCl flux at 1173 K. Its structure is composed of infinite [ScUSe5-]∞2 sheets that are separated by Cs+ ions. The structure contains one Se22- unit per U. Accordingly, the formula is charge balanced with U4+ and Sc3+ as Cs1+Sc3+U4+(Se2-)3(Se22-). From magnetic susceptibility measurements the magnetic behavior of CsScUSe3(Se2) can be divided into three different regions: paramagnetic, T>TN; antiferromagnetic ordering, T<TN; and ferromagnetic, T<Tc, where TN and Tc are approximately 70 K and 25 K, respectively.
