摘要：
The effect of cobalt doping on the structural and dielectric properties of the electron-doped manganite La0.7Te0.3Mn1-xCoxO3 (x= 0, 0.1, 0.3 and 0.5) has been investigated. Cobalt substitution induces a structural transition from rhombohedral structure (R-3 c space group) to orthorhombic structure (Pbnm space group). It is observed that, dielectric constant decreases with Co concentration which could be due to suppression of double exchange (DE) interaction between Mn2+ and Mn3+. Also, the effect of the grain and grain boundary density on the dielectric response is studied using Cole-Cole plots.
