✦ Synopsis

Highly c-axis oriented epitaxial Ru(Eu 1.5 Ce 0.5 )Sr 2 Cu 2 O 10Àd (Ru-1222) thin films were grown on SrTiO 3 (0 0 1) substrates by a novel growth technique, flux-assisted reactive solid phase epitaxy. The films grew epitaxially as (1 0 0)Ru-1222//(1 0 0)SrTiO 3 with excellent crystallinity and atomically flat terraces and steps. The magnetization data are consistent with that reported for bulk Ru-1222 samples. The films are suggested to be granular superconducting. Although zero resistance was not obtained at temperatures down to 5 K, the onset of superconducting transition was observed at about 25 K within the ferromagnetic order.
