Abstract: Single-phase magnetic superconductors RESr2RuCu2O8 (RE=Gd and Eu) were successfully synthesized and investigations on their physical properties were carried out. It is found that the structure of the compounds is similar to that of YBa2Cu3O7 and its superconductivity coexists with weak ferromagnetic order in both compounds. The compounds exhibit magnetic order below TM=130 and 136 K and superconducting below TonsetC=35 and 46 K, respectively, for RE=Eu and Gd samples. There is slight difference in the magnetic properties between RE=Eu and Gd compounds owing to various magnetic moments for Gd3+ and Eu3+.
