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…
Field-driven transition in the BaKFeAs superconductor with splayed columnar defects
Akiyoshi Park, Sunseng Pyon, Kengo Ohara +5
Through 2.6 GeV U irradiations, we have induced bimodal splayed columnar defects in BaKFeAs single crystals with splay angles, , ,…
Effects of heavy-ion irradiation on FeSe
Yue Sun, Akiyoshi Park, Sunseng Pyon +3
We report the effects of heavy-ion irradiation on FeSe single crystals by irradiating Uranium up to a dose equivalent matching field of = 16 T. Almost continuous columnar def…
