The lossless transmission of direct electrical currents in superconductors is very often
regarded as an “energy superhighway” with greatly enhanced efficiency. With the discovery …

REBa 2 Cu 3 O x ((REBCO), RE= rare earth) superconductor tapes with moderate levels of
dopants have been optimized for high critical current density in low magnetic fields at 77 K …

High-temperature superconductors (HTSs) make it possible to achieve magnetic fields
beyond the 23.5 T limit of low-temperature superconductors. For higher energy density, high …

We report on remarkably high in-field performance at 4.2 K achieved in> 4 μm thick rare
earth barium copper oxide (REBCO) samples with Zr addition. Two different samples have …
