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. These results show that a two-step transition in magnetization is related to the secondary peak effect.
