High current-carrying capability in c-axis-oriented superconducting MgB2 thin films
Hyeong-Jin Kim, W. N. Kang, Eun-Mi Choi +3
In high-quality c-axis-oriented MgB2 thin films, we observed high critical current densities (Jc) of 16 MA/cm^2 at 15 K under self fields comparable to those of cuprate high-temper…
Superconducting properties of well-shaped MgB2 single crystal
Kijoon H. P. Kim, Jae-Hyuk Choi, C. U. Jung +11
We report measurements of the transport and the magnetic properties of high-quality, sub-millimeter-sized MgB2 single crystals with clear hexagonal-plate shapes. The low-field magn…
In-plane Hall effect in c-axis-oriented MgB2 thin films
W. N. Kang, Hyeong-Jin Kim, Eun-Mi Choi +4
We have measured the longitudinal resistivity and the Hall resistivity in the ab-plane of highly c-axis-oriented MgB2 thin films. In the normal state, the Hall coefficient (R_H) be…
Fluctuation Magnetoconductance in MgB2
W. N. Kang, Kijoon H. P. Kim, Hyeong-Jin Kim +8
We report fluctuation magnetoconductance in a MgB2 superconductor prepared under a high pressure of 3 GPa. This excess magnetoconductance, , follows the three-dimensional sc…
Effect of sintering temperature under high pressure in the uperconductivity for MgB2
C. U. Jung, Min-Seok Park, W. N. Kang +4
We report the effect of the sintering temperature on the superconductivity of MgB2 pellets prepared under a high pressure of 3 GPa. The superconducting properties of the non-heated…
Hole carrier in MgB_{2} characterized by Hall Measurements
W. N. Kang, C. U. Jung, Kijoon H. P. Kim +7
The longitudinal resistivity rho_{xx} and Hall coefficient R_H were measured for MgB2 sintered under high pressure. We found that R_H is positive like cuprate high-Tc superconducto…
Prominent bulk pinning effect in the MgB_2 superconductor
Mun-Seog Kim, C. U. Jung, Min-Seok Park +4
We report the magnetic-field dependence of the irreversible magnetization of the recently discovered binary superconductor MgB. For the temperature region of , the…
