—Superconducting heterostructures interlayered with a material with strong spin–orbit interaction are studied. As materials with strong spin–orbit interaction, we choose strontium iridates featuring the Ruddlesden–Popper structure (Sr_ n _+ 1Ir_ n O_3 n _+ 1; n = 1, 2, ∞): paramagnetic metal SrIrO_3 and magnetic insulator Sr_2IrO_4. Using laser ablation, epitaxial films of these materials are obtained, as well as heterostructures based on epitaxial films of cuprate superconducting YBa_2Cu_3O_ x . For electrical measurements, mesa-structures of micrometer sizes with top electrodes made of Au/Nb bilayer are fabricated.
