Fabrication of oxide/FeSe multilayer films using the PLD technique
Tomoki Kobayashi, Hiroki Nakagawa, Ryo Ogawa +1
In this study, we demonstrate the successful fabrication of TiO2/FeSe/STO and TiO2/FeSe/LaAlO3 heterostructures using PLD. When the growth rates were sufficiently low, anatase TiO2…

Study on fluctuations of interface-enhanced superconductivity in ultrathin FeSe/SrTiO3 by the Nernst effect
Tomoki Kobayashi, Ryo Ogawa, Atsutaka Maeda
Ultrathin FeSe films on SrTiO3 substrate show interface-enhanced superconductivity. However, how the superconductivity is established including superconducting fluctuations remains…

Study of superconductivity of very thin films investigated by microwave complex conductivity measurements
Gaku Matsumoto, Ryo Ogawa, Koji Higasa +3
Complex conductivity measurements spanning the entire temperature range, including the vicinity of , were conducted on systematically varied FeSeTe ( = 0 - 0.5)…
