Abstract

Multilayer-coated La0.67Sr0.33MnO3/La0.67Ca0.33MnO3(LSMO/LCMO) films can be prepared using cost-effective polymer assisted deposition, keeping a constant LSMO/LCMO volume ratio. By changing the thickness of the individual layers (see figure), the temperature of maximum resistance and the magnitude of magnetoresistance values can be manipulated. Similar properties are not achieved by simply mixing LSMO with LCMO phases at the same volume ratio.
