Studies of superconductivity of Fe chalcogenides in films grown by PLD technique
Atsutaka Maeda, Tomoki Kobayashi, Fuyuki Nabeshima
Studies on Fe chalcogenide superconductor using thin films grown by the PLD technique are reviewed in terms of electronic phase diagram, properties in the normal state, properties…
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…
Nonlinear planar Hall effect from superconducting vortex motion
Mio Hashimoto, Takako Konoike, Tomoki Kobayashi +6
We report the nonreciprocal charge transport along the longitudinal and transverse directions in the vortex flow regime of FeSe superconducting films. Clear nonreciprocal signals u…
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…
