Two-step transition of (Nd0.33Eu0.33Gd0.33)Ba2Cu3Ox superconductors in high fields

Two-step transition of (Nd0.33Eu0.33Gd0.33)Ba2Cu3Ox superconductors in high fields

Superconducting transitions were measured in field-cooled cooling and field-cooled warming modes in external magnetic fields ranging between 0.1 and 7 T on REBa2Cu3Ox superconductors (RE: rare earth elements) with fishtail effect. All the samples exhibited a two-step transition when being cooled in...

Zusammenfassung:Superconducting transitions were measured in field-cooled cooling and field-cooled warming modes in external magnetic fields ranging between 0.1 and 7 T on REBa2Cu3Ox superconductors (RE: rare earth elements) with fishtail effect. All the samples exhibited a two-step transition when being cooled in high fields. Results show that a two-step transition in magnetization is related to the secondary peak effect. 11 refs.
