Effect of cation distribution on the properties of Mn0.2ZnxNi0.8−xFe2O4
Mn0.2ZnxNi0.8−xFe2O4 (x=0.2, 0.3, 0.4, 0.5, 0.6) are synthesized by the citrate precursor method. Effects of zinc substitution on DC resistivity, dielectric relaxation intensity, initial permeability, saturation magnetization ...
Single crystal structures of two new cation-deficient thiospinels: Cu7.38(11)Mn4Sn12S32 and Cu7.07(6)Ni4Sn12S32
Starting from pure metals and sulphur in evacuated silica tubes single crystals of Cu7.38(11)Mn4Sn12S32 and Cu7.07(6)Ni4Sn12S32 have been obtained by quenching from 680 °C. These crystallize in the Fdm space group and have ...
Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 (0≤x≤1): synthesis, structure and dielectric properties
Oxides belonging to the families Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 were synthesized by the solid state reaction route. Sintering temperatures of 1300°C led to oxides with disordered (cubic) perovskite structure. However, ...
