Dielectric Properties of Mn, Co, and Ni-Doped LaSrFeO₃ Films with Different Annealing Atmosphere

Abstract:

Mn, Co, and Ni-doped La_0.5Sr_0.5FeO₃ thin films were prepared by the sol-gel technique with different annesling atmosphere. The structure and dielectric properties of the films were researched by XRD, SEM and Agilent. The study found that LSF-Mn (Co, Ni) films under the argon annealing atmosphere were have optimal dielectric properties. And Mn, Co, Ni elements are integrated into La_0.5Sr_0.5FeO₃ lattices with the single perovskite phase. And uniform grain was distribution on the film surface.
