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…
Superconducting properties and c-axis superstructure of Mg1-xAlxB2
J. Y. Xiang, D. N. Zheng, J. Q. Li +10
The superconducting and structural properties of a series of Mg1-xAlxB2 samples have been investigated. X-ray diffraction results confirmed the existence of a structural transition…
Flux dynamics and vortex phase diagram of the new superconductor
H. H. Wen, S. L. Li, Z. W. Zhao +4
Magnetic critical current density and relaxation rate have been measured on bulks from 1.6 K to at magnetic fields up to 8 Tesla. A vortex phase diagram is depicted b…
Strong quantum fluctuation of vortices in the new superconductor
H. H. Wen, S. L. Li, Z. W. Zhao +6
By using transport and magnetic measurement, the upper critical field and the irreversibility line has been determined. A big separation between $H_{c2}(0)…
Lower Critical Field at Odds with A S-Wave Superconductivity in The New Superconductor
S. L. Li, H. H. Wen, Z. W. Zhao +6
The lower critical field has been carefully measured on a well shaped cylindrical sample of the new superconductor fabricated by high pressure synthesis. The penet…
