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…
Si doping on MgB2 thin films by pulsed laser deposition
Y. Zhao, M. Ionescu, J. Horvat +2
A series of MgB2 thin films were fabricated by pulsed laser deposition (PLD), doped with various amounts of Si up to a level of 18wt%. Si was introduced into the PLD MgB2 films by…
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This paper was withdrawn because subsequent measurements produced results not always consistent with the ones presented in the paper.
Superconducting transition temperature of MgB_2 H_0.03 is higher than that of MgB_2
V. V. Flambaum, G. A. Stewart, G. J. Russell +2
Hydrogenation of MgB_2 powder has lead to an increase in the superconducting temperature, as determined by ac susceptibility. Applied dc fields reduce the transition temperature in…
