Impact of Oxygen Pressure on Ferroelectric Stability of La-doped Hafnia Grown by PLD
Badari Narayana Rao, Shintaro Yasui, Hiroko Yokota
Thin films of HfO2 doped with 4% La were fabricated on LSMO/STO (100) substrates using pulsed laser deposition. The stability of the ferroelectric orthorhombic phase in the hafnia…
Dielectric response of BaTiO3 electronic states under AC fields via microsecond time-resolved X-ray absorption spectroscopy
S. Kato, N. Nakajima, S. Yasui +6
For the first time, the dielectric response of a BaTiO3 thin film under an AC electric field is investigated using time-resolved X-ray absorption spectroscopy at the Ti K-edge to c…
Investigation of Room Temperature Ferroelectricity and Ferrimagnetism in Multiferroic AlxFe2-xO3 Epitaxial Thin Films
Badari Narayana Rao, Shintaro Yasui, Tsukasa Katayama +4
Multiferroic materials open up the possibility to design novel functionality in electronic devices, with low energy consumption. However, there are very few materials that show mul…
Superconducting transition temperatures in the electronic and magnetic phase diagrams of Sr2VFeAsO3-delta, a superconductor
Yujiro Tojo, Taizo Shibuya, Tetsuro Nakamura +13
We elucidate the magnetic phases and superconducting transition temperatures (Tc) in Sr2VFeAsO3-delta (21113V), an iron-based superconductor with a thick-blocking layer fabricated…
Bent Electronic Band Structure Induced by Ferroelectric Polarization
Norihiro Oshime, Jun Kano, Eiji Ikenaga +9
Bent band structures have been empirically described in ferroelectric materials to explain the functioning of recently developed ferroelectric tunneling junction and photovoltaic d…
Anomalous magnetoresistance in the spinel superconductor LiTi2O4
Kui Jin, Ge He, Xiaohang Zhang +9
Transition-metal oxides offer an opportunity to explore unconventional superconductors, where the superconductivity (SC) is often interrelated with novel phenomena such as spin/cha…
Domain tuning in mixed-phase BiFeO3 thin films using vicinal substrates
Lu You, Shintaro Yasui, Xi Zou +6
The structural and ferroelectric domain variants of highly-strained BiFeO3 films grown on vicinal LaSrAlO4 substrates were studied by piezoelectric force microscopy and high-resolu…
