- Abstract
- BaTiO3/La0.7Sr0.3MnOs/BaTiO3 multilayer films are fabricated using the chemical solution deposition and spin-coatingmethod. The upper BT film exhibits an average grain size of approximately 42 nm, indicating a uniform and dense microstructure.
The single-coated film has an average thickness ranging from 40 to 45 nm. A phase transition temperature of approximately4 °C is observed in all films. The BT/LSMO/BT multilayer film, coated with LSMO four times, demonstrates amaximum dielectric constant of 2008 at 20 °C. The BT/LSMO/BT multilayer film, coated with LSMO two times, shows a ΔTof 0.59 K at 24 °C. The remnant polarization, coercive field, and ΔT/ΔE of the BT/LSMO/BT multilayer film, coated withLSMO four times, are 19.8 μC/cm2, 42 kV/cm, and 4.56 mKcm/kV, respectively.
