Modulation of Dirac electrons in epitaxial Bi2Se3 ultrathin films on van-der-Waals ferromagnet Cr2Si2Te6
Takemi Kato, Katsuaki Sugawara, Naohiro Ito +7
We investigated the Dirac-cone state and its modulation when an ultrathin film of topological insulator Bi2Se3 was epitaxially grown on a van-der-Waals ferromagnet Cr2Si2Te6 (CST)…
Unusual temperature evolution of band structure of Bi(111) studied by angle-resolved photoemission spectroscopy and density functional theory
Takafumi Sato, Keiko Yamada, Takao Kosaka +5
We have performed angle-resolved photoemission spectroscopy of Bi(111) thin films grown on Si(111), and investigated the evolution of band structure with temperature. We revealed a…
Origin of magnetovolume effect in a cobaltite
Ping Miao, Zhijian Tan, Sanghyun Lee +21
The layered perovskite PrBaCo2O5.5+x demonstrates a strong negative thermal expansion (NTE) which holds potential for being fabricated into composites with zero thermal expansion.…
First-principles Study on Piezoelectricity and Spontaneous Polarization in Bi(Fe,Co)O3
Hiroshi Katsumoto, Kunihiko Yamauchi, Tamio Oguchi
Solid solution BiFe1-xCoxO3 shows anti-ferromagnetic order and pyroelectric order, simultaneously. It has been known that BiFe1-xCoxO3 exhibits a structural phase transition betwee…
