Quantum Bit Behavior of Pinned Fluxes on Volume Defects in a Superconductor
H. B. Lee, G. C. Kim, Byeong-Joo Kim +2
We studied a qubit based on flux-pinning effects in H=B region of a superconductor. When volume defects are many enough in a superconductor, H=B region on M-H curve is…
Flux-Pinning Behaviors and Mechanism According to Dopant Level in (Fe, Ti) Paticle-Doped MgB Superconductor
H. B. Lee, G. C. Kim, Young Jin Shon +2
We have studied flux-pinning effects of MgB superconductor by doping (Fe, Ti) particles of which radius is 163 nm on average. 5 wt.\% (Fe, Ti) doped MgB among the specimens…
Water-Quenched Effects of 5 wt.% (Fe, Ti) particle-doped MgB Superconductor and Low Limit of Pinning Effect
H. B. Lee, G. C. Kim, Hyoungjeen Jeen +1
\begin{abstract} We have studied magnetic properties of water-quenched 5 wt.% (Fe, Ti) particle-doped MgB comparing with that of air-cooled one. Generally, grain refinement is…
Upper Critical Field Based on the Width of H = B region in a Superconductor
H. B. Lee, G. C. Kim, B. J. Kim +1
We studied a method of measuring upper critical field (H) of a superconductor based on the width of H = B region, which appears in the superconductor that volume defec…
Delta H = Delta B region in volume defect-dominating superconductor
H. B. Lee, G. C. Kim, H. J. Park +1
According to Ginzburg-Landau theory, it has been generally accepted that the diamagnetic property decreases after the lower critical field. However, we found that (Fe, Ti) particle…
Observation of spin-orbit insulator-like behavior in LaOBiSF (0.05 0.2)
G. C. Kim, M. Cheon, Y. C. Kim +1
We report the effects of electron doping on the crystal structure and electrical resistivity of LaOBiSF (0.05 0.2). The plane is found to be rela…
Doping dependence of phase coherence between superconducting BiSrCaCuO grains
G. C. Kim, M. Cheon, Y. C. Kim
In the present work, we report the new findings on the doping level dependence of the phase coherence between superconducting BiSrCaCuO (Bi-2212) grains. The ex…
A ferromagnetic-like phase transition in new oxychalcogenide HgOCuSe
G. C. Kim, M. Cheon, I. S. Park +2
We report the synthesis of a new oxychalcogenide HgOCuSe sample. The resistivity decreases as a function of with decreasing temperature from room temperature down to aro…
