We review experimental studies of the time decay of the nonequilibrium magnetization in
high-temperature superconductors, a phenomenon known as magnetic relaxation. This …

Abstract Iron-based superconductors (IBSs), discovered in 2008, formed the second high-T c
superconductor family after cuprate superconductors, and over the past decade have been …

Pressure‐stabilized hydrides are a new rapidly growing class of high‐temperature
superconductors, which is believed to be described within the conventional phonon …

Recent discoveries of superconductivity in various hydrides at high pressures have shown
that a critical temperature of superconductivity can reach near-room-temperature values …

Cuprate superconductors are key candidate materials toward high energy-efficient devices.
Improving their growth rate and performance under magnetic fields are indispensable for …

Magnetic flux can penetrate a type-II superconductor in the form of Abrikosov vortices (also
called flux lines, flux tubes, or fluxons) each carrying a quantum of magnetic flux phi 0= h/2e …

In the past few years magneto-optical flux imaging (MOI) has come to take an increasing role
in the investigation and understanding of critical current densities in high-T c …

Detailed measurements of the critical current density jc of YBa 2 Cu 3 O 7− δ films grown by
pulsed laser deposition reveal the increase of jc as a function of film thickness. Both this …

Current densities js and volume pinning forces F p are obtained in a wide temperature (5<~
