Enhanced pinning in high-temperature superconducting cuprate single crystals at low magnetic field
Low density flux dynamics in Nd based cuprate (NdBa₂Cu₃O₇₋x) HTSC single crystals trapped in ≈1 Oe range DC magnetic fields were investigated for the first time. Complex measurements of time, temperature and field dependence of magnetization were performed. Using the results obtained and the Anderso...
