Anisotropies and Homogeneities of Superconducting Properties in Iron-Platinum-Arsenide Ca10(Pt3As8)(Fe1.79Pt0.21As2)5
Qing-Ping Ding, Yuji Tsuchiya, Yue Sun +3
We report a study on the anisotropy of superconducting properties in single crystalline Ca10(Pt4-δAs8)(Fe1.79Pt0.21As2)5 with Tc ~13.6 K. Under a field of 5 Oe, the sample reaches…
Enhancement of critical current density and vortex activation energy in proton-irradiated Co-doped BaFe2As2
Toshihiro Taen, Yasuyuki Nakajima, Tsuyoshi Tamegai +1
The effect of proton irradiation in Ba(Fe0.93Co0.07)2As2 single crystals is reported. We analyze temperature dependence of current density and normalized flux relaxation rate in th…
Magnetic and transport properties of iron-platinum arsenide Ca10(Pt4-δAs8)(Fe2-xPtxAs2)5 single crystal
Qing-Ping Ding, Yuji Tsuchiya, Shyam Mohan +3
We report superconducting properties of single crystalline Ca10(Pt4-δAs8)(Fe2-xPtxAs2)5 by X-ray diffraction, magnetization, resistivity, and magneto-optical imaging measurements.…
Superconducting properties and magneto-optical imaging of Ba0.6K0.4Fe2As2 PIT wires with Ag addition
Qing-Ping Ding, Trirat Prombood, Yuji Tsuchiya +2
We have fabricated (Ba,K)Fe2As2 superconducting wires through ex-situ powder-in-tube method. Silver was used as a chemical addition to improve the performance of these superconduct…
