Three methods were used to introduce flux-pinning centers into Bi2Sr2CaCu2Ox (Bi-2212) and TlBa2Ca2Cu3Ox (Tl-1223) samples. It was found that carbon induced local decomposition, that nanosized Al2O3 additions created stable reaction products, and that second phases could be isolated in Tl-1223 during synthesis. Each of these defects enhanced flux pinning and was of most benefit at temperatures ≤ 35K.
