GdSr₂RuCu₂O_8-d (Gd1212) Rutheno-Cuprate Superconductor is known to show both superconducting and magnetically ordered phases coexisting in the same cell. To investigate its still controversial superconducting and magnetic features, the fabrication of macroscopic crystallographically oriented samples is necessary. The use of melt texturing techniques has shown to be among the most effective ways to produce Gd1212 samples with the best characteristics, even due to the unavailability of single crystals. Anyway, Gd1212 synthesis and the fabrication of high-quality samples are intrinsically difficult. A better understanding of incongruent melting reaction is then needed.
