Effects of 3 MeV Proton Irradiation on Superconductivity and CDW in 2H-NbSe2 Single Crystals
Wenjie Li, Sunseng Pyon, Akiyoshi Yagi +8
Interplay between superconductivity and charge-density wave (CDW) in 2H-NbSe2 single crystals irradiated by 3 MeV protons is studied. Both Tc and TCDW are found to decrease monoton…
Effects of asymmetric splayed columnar defects on the anomalous peak effect in BaKFeAs
Ayumu Takahashi, Sunseng Pyon, Tadashi Kambara +2
In order to enhance the critical current density () of superconductors, introduction of columnar defects (CDs) through swift-particle irradiation is effective. By dispersing t…
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…
