摘要：

YBa2Cu3O7-δ　(YBCO)　films　with　SrZrO3　doping　were　prepared　successfully　by　a　non-vacuum,　low　cost,　and　easily　scalable　metal-organic　deposition　method,　and　their　microstructures　and　physical　properties　were　investigated.　From　the　analysis　of　XRD　and　φ-scan　results,　the　doped　films　had　sharp　biaxial　textures.　Although　the　doped　YBCO　film　had　a　larger　ΔTc　than　that　of　the　un-doped　YBCO　film,　a　very　significant　enhancement　of　Jc　was　displayed　as　compared　to　the　un-doped　film　with　increasing　magnetic　field　and　temperature,　indicating　that　an　effective　pinning　force　was　created　by　SrZrO3　doping.　These　results　clearly　exemplify　the　appealing　application　prospects　for　the　doped　film　in　high　magnetic　fields　and　temperatures.
