Description |
PbTiO3 (PT) and La/Mn modified PbTiO3 (PLMT) nanoceramics were prepared by mechanical alloying and thermal methods. A thermal analysis technique has provided some important clues and guidelines for formation of required compounds and their thermal stability. The formation of single-phase perovskite compounds was confirmed by an X-ray diffraction technique. The field emission scanning electron micrograph of the compounds shows that materials have well-defined granular morphology. La/Mn substitution at Pb/Ti sites reduces the lattice distortion, and decreases ferroelectric phase temperature of lead titanate. Room temperature P-E loop confirms the existence of ferroelectric ordering in the sample. The nonlinear M-H hysteresis loop with small magnetization revealed that a ferromagnetic property is observed in PbTiO3 clue to the substitution of Mn at Ti-sites of PbTiO3 (C) 2014 Elsevier B.V.
