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…
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This paper was withdrawn because subsequent measurements produced results not always consistent with the ones presented in the paper.
Improvement of critical current in MgB2/Fe wires by a ferromagnetic sheath
J. Horvat, X. L. Wang, S. Soltanian +1
Transport critical current (Ic) was measured for Fe-sheathed MgB2 round wires. A critical current density of 5.3 x 10^4 A/cm^2 was obtained at 32K. Strong magnetic shielding by the…
