The superconducting state of an infinitely long superconducting cylinder surrounded by a medium which enhances its superconductivity near the boundary is studied within the nonlinear Ginzburg-Landau theory. This enhancement can be due to the proximity of another superconductor or due to surface treatment. Quantities such as the free energy, the magnetization and the Cooper-pair density are calc...

Non-resonant microwave absorption(NRMA) studies of superconducting MgB2 at a frequency of 9.43 GHz in the field range -50 Gauss to 5000 Gauss are reported. The NRMA results indicate near absence of intergranular weak links. A linear temperature dependence of the lower critical field H c 1 is observed indicating a non s-wave superconductivity. However, the phase reversal of the NRMA signal which...

We report the magnetoresistance in novel spin-triplet superconductor UTe2 under pressure close to critical Pc, where superconducting phase terminates, for field along three a, b and c-axes orthorhombic structure. The H // a-axis just below Pc shows a field-reentrant behavior due competition with emergence of magnetic order at low fields. upper Hc2 c-axis quasi-vertical increase H-T diagram indi...

This paper reports on the integration of publicly available HTS conductor electromagnetic performance data into a magnetic Finite Element model for determining critical current distribution along section in spatially fluctuating field. The simulation results from this are shown to be close agreement experimentally obtained results. Typically monitoring quench is done by measuring volt-drop prot...
