Evolution of Critical Current Density in CaKFeAs with La-doping
Yangsong Chen, Chunlei Wang, Yuhang Zu +4
Single crystals of (CaLa)KFeAs (0 <= x <=0.16) have been grown by using the self-flux method, and the evolution of physical properties including the critical cu…
Crossover between Anomalous Peak Effects Induced by Splayed and Tilted Columnar Defects in BaKFeAs
Kanta Kato, Ryosuke Sakagami, Satoru Okayasu +2
We investigated the magnetic field dependence of the critical current density (Jc) in Ba0.6K0.4Fe2As2 with various configurations of columnar defects (CDs) introduced by 2.6 GeV U…
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…
Ferromagnetic levitation and harmonic trapping of a milligram-scale Yttrium Iron Garnet sphere
Maria Fuwa, Ryosuke Sakagami, Tsuyoshi Tamegai
We report passive magnetic levitation and three-dimensional harmonic trapping of a 0.3 milligram, 0.5 millimeter diameter Yttrium Iron Garnet sphere at 4 K. The gradient of an exte…
Spintronic superconductor in a bulk layered material with natural spin-valve structure
Shunsuke Sakuragi, S. Sasaki, R. Akashi +29
Multi-layered materials provide fascinating platforms to realize various functional properties, possibly leading to future electronic devices controlled by external fields. In part…
Synthesis, Crystal Structure, and Thermoelectric Properties of Layered Antimony Selenides REOSbSe2 (RE = La, Ce)
Yosuke Goto, Akira Miura, Ryosuke Sakagami +4
Inspired by the recent first-principles calculations showing the high thermoelectric performance of layered pnictogen chalcogenides, we experimentally characterise the crystal stru…
