The　Y0.5Gd0.5BCO　film　was　successfully　fabricated　by　fluorine-reduced　MOD　method　through　dissolving　Gd(CH3COO)(3)　into　the　precursor　solution.　As　a　result,　Y　was　partially　substituted　by　Gd　and　all　the　films　have　well　c-axis　orientation.　By　comparing　the　superconducting　properties,　it　is　found　that　the　Y0.5Gd0.5BCO　film　has　lower　critical　transition　temperature　T-c　(90.5K)　than　that　of　the　pure　YBCO　and　GdBCO　films.　Yet　the　Y0.5Gd0.5BCO　film　has　the　highest　critical　current　density　J(c)　value　about　4.87MA/cm(2)　at　65K　and　self-field.　In　addition,　the　J(c)　value　of　Y0.5Gd0.5BCO　film　is　enhanced　significantly　as　increasing　the　applied　magnetic　field.　The　J(c)　value　of　Y0.5Gd0.5BCO　film　is　1.8　times　and　5.1　times　of　that　of　the　pure　GdBCO　and　YBCO　films　at　65K　and　3T　applied　field,　respectively.　Furthermore,　the　pinning　force　of　the　Y0.5Gd0.5BCO　film　is　effectively　improved　by　the　elemental　substitutions.
