Magnetic relaxation and critical current density of thin films
H. H. Wen, S. L. Li, Z. W. Zhao +6
Magnetic relaxation and critical current density have been measured on a thin film in a wide region of temperature with the magnetic field up to 8 T. The irreversibility li…
Dendritic flux patterns in MgB2 films
T. H. Johansen, M. Baziljevich, D. V. Shantsev +7
Magneto-opitcal studies of a c-oriented epitaxial MgB2 film with critical current density 10^7 A/cm^2 demonstrate a breakdown of the critical state at temperatures below 10 K [cond…
Anisotropic Superconductivity in Epitaxial MgB2 Films
M. H. Jung, M. Jaime, A. H. Lacerda +5
High-quality epitaxial MgB2 thin films prepared by pulsed laser deposition with Tc = 39 K offer the opportunity to study the anisotropy and robustness of the superconducting state…
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…
Temperature- and magnetic-field-dependent resistivity of MgB2 sintered at high temperature and high pressure condition
C. U. Jung, Min-Seok Park, W. N. Kang +3
We report the temperature- and magnetic-field-dependent resistivity of MgB2 sintered at high temperature and high pressure condition. The superconducting transition width for the r…
Current responses and voltage fluctuations in Josephson-junction systems
Mahn-Soo Choi, M. Y. Choi, Sung-Ik Lee
We consider arrays of Josephson junctions as well as single junctions in both the classical and quantum-mechanical regimes, and examine the generalized (frequency-dependent) resist…
