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…
Comparative study of in situ and ex situ MgB2 films deposited by pulsed laser deposition
Y. Zhao, M. Ionescu, J. Horvat +1
Two types of MgB2 films were prepared by pulsed laser deposition (PLD) with in situ and ex situ annealing processes respectively. Significant differences in properties between the…
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
