Abstract
(Mn1.56Co0.96Ni0.48O4)1 â x(LaMnO3)x serial thin films have been synthesized on Si substrates through the chemical solution deposition method. The film crystal structures varied from a pure spinel phase to a mixed perovskite/spinel phase according to the increase in La concentration. Similarly, film density and surface roughness were improved with an increase in La concentration. According to the optical constant spectra of the composite thin films, two strong absorption structures appeared in the visible spectral range. Resistance-temperature curves indicated that all of the prepared thin films have negative temperature coefficient effects. In particular, the x = 0.5 film offered the lowest resistance and highest B25/50 constant at 4022 K, compared with the remaining films.
