Effects of asymmetric splayed columnar defects on the anomalous peak effect in Ba $_{0.6}$ K $_{0.4}$ Fe $_{2}$ As $_{2}$

Ayumu Takahashi, Sunseng Pyon, Tadashi Kambara +2

In order to enhance the critical current density ( $J_{c}$ ) of superconductors, introduction of columnar defects (CDs) through swift-particle irradiation is effective. By dispersing t…

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…
