We investigated the effects of indium doping on the superconducting properties of YBCO sintered samples and thin films. In₂O ₃-doped YBCO and YBa₂Cu_{3 x}In_xO _y sintered samples showed a gradual decrease in the critical temperature (T_c) with increasing indium content; however, a T _c value above 80 K was maintained even up to 30 vol.% addition and x = 0.4, respectively. Ba₃Cu₃In₄O₁₂ was detected by X-ray diffractometry and energy-dispersive X-ray spectroscopy as a reaction product for both sintered samples. The normalized J_c under a magnetic field of 0.1 T showed a maximum at x = 0.3. Indium-doped YBCO films prepared by pulsed laser deposition showed a similar dependence of T _c on indium content as the sintered samples.
