Flux pinning mechanism in NdFeAsO0.82F0.18 superconductor: Thermally activated flux flow and charge carrier mean free path fluctuation pinning
X. L. Wang, S. R. Ghorbani, S. X. Dou +4
The flux pinning mechanism of NdO0.82F0.18FeAs superconductor made under high pressure, with a critical temperature, Tc, of 51 K, has been investigated in detail in this work. The…
Superconducting screening on different length scales in high-quality bulk MgB2 superconductor
J. Horvat, S. Soltanian, A. V. Pan +1
High quality bulk MgB2 exhibit a structure of voids and agglomeration of crystals on different length-scales. Because of this, the superconducting currents percolate between the vo…
The effect of sample size on field dependence of Jc for MgB2 superconductor
J. Horvat, S. Soltanian, X. L. Wang +1
A strong effect of sample size on magnetic Jc(H) was observed for bulk MgB2 when Jc is obtained directly from the critical state model. Thus obtained zero-field Jc (Jc0) decreases…
Superconductivity, critical current density, and flux pinning in MgB_{2-x}(SiC)_{x/2} superconductor after SiC nanoparticle doping
S. X. Dou, A. V. Pan, S. Zhou +5
We investigated the effect of SiC nano-particle doping on the crystal lattice structure, critical temperature T_c, critical current density J_c, and flux pinning in MgB_2 supercond…
Paramagnetic Meissner effect in MgB2 superconductor
J. Horvat, X. L. Wang, S. Soltanian +1
This paper was withdrawn because subsequent measurements produced results not always consistent with the ones presented in the paper.
Enhancement of Flux Pinning in Neutron Irradiated MgB Superconductor
E. Babic, Dj. Miljanic, K. Zadro +5
m-H loops for virgin and neutron irradiated bulk and powder samples of MgB_{2} were measured in the temperature range 5-30 K in magnetic field B<= 1 T. The irradiation at thermal n…
