disclosed herein are a textured ag sheet and an hts tl - 1223 phase coated conductor featuring a high critical current density . the ag sheet is allowed to have an intensified texture by applying an additional tensile force to an ag sheet which has undergone primary recrystallization . the hts tl - 1223 phase coated conductor is fabricated by depositing / layering a biaxially textured tl - 1223 phase hts film on the ag substrate . the application of a slight tensile force suppresses the occurrence of secondary recrystallization in the ag sheet , resulting in the intensification of texture components in the ag sheet .
