Abstract

Pb(Zr0.52Ti0.48)O3/La0.8Ca0.2MnO3 (PZT/LCMO) thin films were deposited onto SrTiO3 (STO) single crystalline substrates by pulse laser deposition (PLD). The AFM morphology results show that the LCMO ( PZT) layer is very smooth and homogenous with very low values of RMS roughness. The XRD results show that only the (00l) peaks are observed for both LCMO and PZT layers which are single crystalline and have an epitaxial relationship with STO substrates: PZT (001)//LCMO(001)//STO (001). The FWHM values of the (001) omega-rocking curves of the LCMO and PZT film were 0.276o and 0.565o, respectively, which suggests high crystalline quality of epitaxial PZT/LSMO LSMO heterostructures were grown on STO substrates.
