Abstract

We investigated superconducting YBa₂Cu₃O₇ (YBCO), insulator SrTiO₃ (STO), and ferromagnetic La_2/3Ca_1/3MnO₃ (LCMO) multilayered heterostructures grown by pulsed laser deposition (PLD) on h100i YSZ substrates. These hybrid structures have demonstrated strong superconducting properties, similar to those of YBCO films, with a minimum influence of the ferromagnetic layer. We report unusual transport properties and negative differential resistance above the superconducting transition. The electro- and magnetoresistance effects observed in a hybrid YBCO micro-bridge with a top LCMO layer may be the consequence of phase separation induced by electric current.
