Bi $_{0.5}$ Na $_{0.5}$ TiOBaTiO (BNTBT) solid solutions have been extensively studied because they exhibit good piezoelectric properties. In addition, a wide variety of phases are observed depending on the BT composition. Soft X-ray absorption spectroscopy and high-energy X-ray diffraction experiments of BNTBT solid solutions were performed using synchrotron radiation. From the electronic structure and local structure of BNTBT solid solution, the substitution effect of BT occurred mainly at the A site, which is the substitution site of Ba. The rhombohedral strain of the TiO octahedron did not change with the change in BT composition, suggesting that the change in the electronic structure at the O- absorption edge is due to the change in the hybridization state.

Creating a bipolarity of semiconductors has been a key technology to develop recent advanced semiconductor devices. Although theoretical calculation predicts the presence of ferromagnetic electron-doped manganites with doping tetravalent cations, the ferromagnetic origin in experiments has been controversial due to the lack of direct experimental evidence. Here, we investigate the ferromagnetism in (La,Ce)MnO $_{3}$ thin films by measuring the magnetic circular dichroism in soft X-ray absorption (XMCD). The XMCD measurements clarified that the ferromagnetism is not caused by the presence of Mn $^{2+}$ but by self-hole doping for manganese.
