YBa₂Cu₃O _x superconducting nanorods

Herein, we report the synthesis of YBa₂Cu₃O _x superconducting nanorods performed by solution chemistry. Initially, a mixture of fine-grained coprecipitated powder was obtained and subsequently converted to YBa₂Cu₃O _x nanorods by heating to 1223 K in oxygen for 12 h. The nanorods are superconducting without the need for any further sintering or oxygenation, thereby providing an avenue for direct application to substrates at room temperature or direct use as formed nanorods. A critical superconducting transition temperature T _c of about 92 K was achieved at a critical magnetic field of 10 Oe.
