“…Lanthanum strontium cobalt oxide, La 0.5 Sr 0.5 CoO 3 (LSCO) films are used as oxide electrodes for ferroelectric memory devices. A solution made from, La, Sr, Co nitrate with polyvinyl alcohol has been reported [107], and a crystalline perovskite phase was obtained by annealing at 650 • C. Sodium bismuth titanate, Na 0.5 Bi 0.5 TiO 3 (NBT), ceramics are useful materials for piezoelectric, optic-electric and pyroelectric applications. Titanium isopropoxide, NaNO 3 and Bi(NO 3 ) 3 precursors were used to prepare the NBT precursor solution by Lin et al [108].…”
