## Abstract Columnar single crystals of Feβdoped Ca~3~Co~2~O~6~ with a pseudoβoneβdimensional structure were synthesized by a flux method using K~2~CO~3~. Seebeck coefficient (__S__ ) and electrical resistivity (__Ο__ ) of an Feβdoped Ca~3~Co~2~O~6~ single crystal along the elongated direction were
In-doped ZnFe 2 O 4 nanoparticles were prepared by a co-precipitation method. The nanoparticles were charactarized by conventional powder Xray diffraction, energy dispersive X-ray spectrometry, transmission electron microscopy, Raman and MΓΆssbauer spectroscopy. It was found that Zn 1-x In x Fe 2 O 4
