Abstract

Heterostructures of non-magnetic/magnetic high T_c superconductors have been grown by laser ablating pure YBaCuO and Ni doped YBaCuO. Superconducting properties of the composite are dependent on the amount of doping and the thickness of the doped layers. The critical temperatures of 87K and critical current densities in excess of 10⁶ A/cm² at 77K in 0.85 Tesla magnetic fields have been obtained for structures grown on ZrO₂ substrates.
