Optical Properties of LiNbO thin films
T. Kurachi, T. Yamaguchi, E. Kobayashi +3
The complex dielectric functions of LiNbO were determined using optical transmittance and reflectance spectroscopies at room temperature. The measured dielectric function spect…
Modulation of magnetic property of double-perovskite La2MnCoO6 films by controlling B-antisite disorder
R. C. Sahoo, S. Zhang, Y. Takeuchi +6
The predicted physical properties of double perovskites have usually been compromised by their intrinsic B-antisite (AS) disorder effect, but the relationship between them is still…
Electronic properties across metal-insulator transition in β-pyrochlore-type CsW2O6 epitaxial films
Takuto Soma, Kohei Yoshimatsu, Koji Horiba +2
In CsW2O6, which undergoes a metal-insulator transition (MIT) at 213 K, the emergence of exotic properties associated with rattling motion of Cs is expected owing to its characteri…
Superconductivity in higher titanium oxides
K. Yoshimatsu, O. Sakata, A. Ohtomo
Recent renewal of the highest transition temperature in a conventional superconductor of the sulfer hydride attracts much attention to exploring simple compounds with the lighter e…
Insulator to metal transition of WO3 epitaxial films induced by electrochemical Li-ion intercalation
Kohei Yoshimatsu, Takuto Soma, Akira Ohtomo
We investigated systematic evolutions of structural and electronic properties of LixWO3 films, induced by Li-ion electrochemical reactions. Chronoamperometric Li-ion intercalation…
Epitaxial growth of hexagonal tungsten bronze CsxWO3 films in superconducting phase region exceeding bulk limit
Takuto Soma, Kohei Yoshimatsu, Akira Ohtomo
We report epitaxial synthesis of superconducting CsxWO3 (x = 0.11, 0.20, 0.31) films on Y-stabilized ZrO2 (111) substrates. The hexagonal crystal structure was verified not only fo…
