다국어 초록 (Multilingual Abstract)

MgB2 thin films with superior superconducting properties are very promising for superconducting magnets, electronic devicesand coated conductor electric power applications. A clear understanding of flux pinning mechanism in MgB2 films could be a bigaid in improving the performance of MgB2 by the enhancement of Jc. The fabrication advancement and the understanding of fluxpinning mechanism of MgB2 thin and thick films fabricated by using hybrid physical-chemical vapor deposition (HPCVD) arereviewed. The distinct kind of MgB2 films, such as single-crystal like MgB2 thin films, MgB2 epitaxial columnar thick films, anda-axis-oriented MgB2 films are included for flux pinning mechanism investigation. Various attempts made by researchers toimprove further the flux pinning property and Jc performance by means of doping in MgB2 thin films by using HPCVD are alsosummarized.
