Ferroic metal-oxide films grown by polymer assisted deposition

Polymer assisted deposition is a versatile technique to grow simple and complex metal-oxide thin films. In this paper we report the structural and electrical properties of ferroic materials, namely La0.67M0.33MnO3 (M=Sr and Ca) and Ba1 −xSrxTiO3 (x=0.3, 0.5, and 0.7) prepared using this process. The films were prepared on single crystalline LaAlO3 substrates. The films were highly c-axis oriented and epitaxial in nature. The ferromagnetic La0.67Sr0.33MnO3 and La0.67Ca0.33MnO3 films show intrinsic transport properties with maximum magnetoresistance values (at applied field of 5 T) of −50% and −88%, respectively. The highest dielectric constant (∼1010) and tunability (∼69%) of Ba1 −xSrxTiO3 film occurs at x=0.3 for films, which is at the phase boundary of tetragonal and cubic. Published by Elsevier B.V.
