Notes
- Lao.5Sro.5Co03 (LSCO) and La0.67Ca0.33MnO3 (LCMO) films were prepared by sol-gel techniques and their structural and transport properties investigated. Films were spin-coated onto (001) LaAlO3 (LAO), (001) SrTiO3 (STO), Pt/TiO2/SiO2/Si, and Al2O3 substrates, and ictural properties were investigated using X-ray diffraction, scanning and transmission electron microscopy (SEM and TEM). SEM studies showed that the films were crack-free and adhered well to the substrates. No preferential orientation of the pervoskite films was observed on Si- or Pt/TiCVSiCVSi-substrates, but films deposited on LAO and STO showed good alignment with the substrate. Transport measurements of epitaxial LCMO films show maximum temperature coefficient of resisth (TCR) of 6.1 % K1 aät 241 K and colossal magnetoresistance (CMR) of 32 % a at 246 K. The conductivity of around l .9 mQcm.
