dc.description.abstract Zr-doped REBa2Cu3O7-x (REBCO and RE = Gd, Y in this thesis) coated conductors fabricated by the Metal Organic Chemical Vapor Deposition (MOCVD) method has demonstrated excellent in-field performance at 77K and a low magnetic field in previous research. However, the most important and promising applications of HTS coated conductors requires excellent in-field performance at various cryogenic temperatures between 77K and 20K, or even lower temperatures, with a high external magnetic field. In this thesis, REBCO coated conductor samples with different Zr contents (0%-15%) fabricated by the MOCVD method were systematically studied in a series of electromagnetic measurements at a wide range of temperatures and fields. Interesting pinning effects of various Zr-doping levels were observed across the temperature and field range. In order to interpret these pinning phenomena, microstructural analysis was done using SEM and TEM methods to reveal the influence of temperature, field and chemical composition on the performance and microstructure of Zr-doped REBCO coated conductors.
