| Abstract: | Different Nb doped Ca0.9Yb0.1Mn1-xNbxO3 ceramics are successfully synthesized by the conventional solid state reaction technique.The crystal structures are of orthorhombic phase,belonging to the Pnma space group.The lattice constant and the volume increase with the increase of Nb content.Relatively high density is around 97%.Scanning electron microscope (SEM) images show that samples are well crystallized.The electrical resistivity and the Seebeck coefficient are measured in a temperature range between 300 ... |
