Peak Effects Induced by Particle Irradiations in 2H-NbSe2
Wenjie Li, Sunseng Pyon, Akiyoshi Yagi +5
Various peak effects in 2H-NbSe2 single crystals induced by particle irradiations were studied. 3 MeV proton irradiation magnified the peak effect induced by order-disorder transit…
Suppression of Superconductivity in Heavy-ion Irradiated 2H-NbSe2 Caused by Negative Pressure
Wenjie Li, Sunseng Pyon, Ataru Ichinose +2
Effects of columnar defects created by 320 MeV Au irradiation on 2H-NbSe2 single crystals with a dose equivalent matching field up to 16 T were studied. Critical temperature is fou…
Sulfur-induced magnetism in FeSeS thin films on LaAlO revealed by muon spin rotation/relaxation
F. Nabeshima, Y. Kawai, N. Shikama +8
Muon spin rotation/relaxation measurements were performed to investigate magnetic properties of FeSeS thin films on LaAlO. A drastic decrease of the initial asymmet…
Anisotropic physical properties and large critical current density in KCaFeAsF single crystal
Sunseng Pyon, Yuto Kobayashi, Ayumu Takahashi +7
We present a systematic study of electrical resistivity, Hall coefficient, magneto-optical imaging, magnetization, and STEM analyses of KCaFeAsF single crys…
Large and significantly anisotropic critical current density induced by planar defects in CaKFe4As4 single crystals
Sunseng Pyon, Ayumu Takahashi, Ivan Veshchunov +8
Three independent components of critical current density, one for the H//c axis and the other two for the H//ab plane, have been studied in CaKFe4As4 single crystals. When the magn…
Superconductivity at 38 K in an electrochemical interface between ionic liquid and Fe(Se0.8Te0.2) on various substrates
Shunsuke Kouno, Yohei Sato, Yumiko Katayama +6
Superconducting FeSe0.8Te0.2 thin films on SrTiO3, LaAlO3 and CaF2 substrates were electrochemically etched in an ionic liquid DEME-TFSI electrolyte with a gate bias of 5 V. Superc…
