Sol-gel fabrication of samarium and manganese modified lead titanate thin films and ceramics

Samarium and manganese modified lead titanate thin films were deposited on Pt coated Si (100) substrates by spin coating using a precursor solution prepared from Pb, Sm and Mn acetates and Ti-isopropoxide with acetic acid and n-propanol as solvents. The gel powder on heat treatment showed (101) as t...

Beschreibung
Zusammenfassung:	Samarium and manganese modified lead titanate thin films were deposited on Pt coated Si (100) substrates by spin coating using a precursor solution prepared from Pb, Sm and Mn acetates and Ti-isopropoxide with acetic acid and n-propanol as solvents. The gel powder on heat treatment showed (101) as the highest intensity peak while the thin films deposited on Pt coated silicon substrates showed a preferential orientation of (100). These films after being annealed at 900 °C for 1 h showed good remanent polarization and coercive fields.
