GdSr₂RuCu₂O_8-d (Gd1212) is known to show both superconducting and magnetic ordered phases coexisting in the same cell. To study these unconventional features, macroscopic crystallographically oriented samples are needed. But Gd1212 synthesis and the fabrication of high-quality samples are intrinsically difficult, so the most effective way to achieve the best properties (even due to the unavailability of single crystals) appears to be via melt texturing techniques. A better understanding of melting reaction is then needed.
