Abstract:The upper critical field of REBa2Cu3O7-δ（REBCO，RE=Y, Gd, Sm, Nd, etc）superconducting materials can reach up to 100 T, presenting great potential in high-power applications. However, it faces the challenge of a sharp decline in critical current density under high-temperature and high-magnetic-field conditions. The introduction of effective artificial pinning centers (APCs) into this material is key to enhancing flux pinning and improving current-carrying capacity. This paper reviews the research progress in constructing multi-dimensional pinning centers in REBCO superconductors through chemical doping and microstructure engineering. It details the fetures of various artificial pinning technologies—such as element doping, substrate surface modification, particle irradiation, and second-phase doping—as well as their effects on properties including critical current density and trapped magnetic field. Finally, the future research directions of artificial flux pinning techniques for REBCO superconductors are prospected.
