| contents | This study investigates the synthesis of novel magnetic materials via hydroflux synthesis, a method that combines flux-based and hydrothermal techniques. Single crystals of three novel alkali tellurate oxide hydroxides were synthesized. One, CsTeO3(OH), is nonmagnetic and a new member of the series ATeO3(OH) (A = alkali). The other two phases contain magnetic Cu-Te substructures, one of which, KCu2Te3O8(OH), is structurally three-dimensional and undergoes several magnetic ordering transitions. The other, Cs2Cu3Te2O10, is structurally two-dimensional and remains paramagnetic above T = 2 K. These exploratory investigations of novel phase spaces reveal key factors, including hydroxide concentration, precursor solubility, and oxidizing power of the solution, in the formation and composition of alkali tellurate oxide hydroxides. |
