Abstract
The magnetic properties of high Tc superconductor (HTS) SmBa2Cu3O7−δ (SmBCO) coated conductors (CCs) which are based on IBAD (ion-beam-assisted deposition) templates were investigated. The SmBCO CCs were fabricated on LaMnO3(LMO)/epi-MgO/IBAD-MgO/Hastelloy substrates by Evaporation using Drum in Dual Chamber (EDDC) processing. The measurements of isothermal magnetizations M(H) for the prepared SmBCO-CCs were carried out at various temperatures in magnetic fields up to 8.5T. The magnetic properties for the applied magnetic fields parallel to the ab-plane show non-conventional behaviors when compared to those parallel to both c-axis and c-axis+45°. These normal and anomalous properties can be explained by introducing the magnetic flux pinning effects related to the direction of the applied magnetic fields.
