Title: Thickness-dependent charge ordering state in Bi{sub 0.4}Sr{sub 0.28}Ca{sub 0.32}MnO{sub 3} thin films under the anisotropic strain

Abstract

We have achieved clear charge ordering (CO) state in Ca doped Bi{sub 0.4}Sr{sub 0.6−x}Ca{sub x}MnO{sub 3} (BSCMO) films on (110)-orientated SrTiO{sub 3}. The BSCMO film's CO transition temperature (T{sub CO}) was tuned to room temperature (RT) by optimum doping Ca (x = 0.32). Asymmetric x-ray reciprocal space mapping was used to determine the structure evolution of the films with thickness, in detail, under the anisotropic stress in films. We found that the CO phase only appears in thicker films, accompanied by an unique distortion in structure, in which twin-domains structure occurs with the [110] axis slightly tilting toward [1–10] and [−110] directions. The results demonstrate the effects of anisotropic stress on the structure and electronic phases in BSCMO films as thickness increases. Our works are valuable for allowing a RT study in the CO film and further operation of the devices for a practical use.
