Single-crystalline Mg2TiO4 layers have been employed as a novel substrate material for superconducting YBa2Cu3O7−δ (YBCO) thin films. The Mg2TiO4 substrate layers have been grown on MgO cleavage faces by a solid-state reaction between the MgO crystal and TiO2 vapor. The structure and morphology of laser-deposited YBCO thin films have been studied by x-ray diffraction, transmission electron microscopy, electron diffraction, and scanning tunneling microscopy. YBCO has been grown on Mg2TiO4(001) with the epitaxial relationship [100](001) YBCO (parallel)[100](001)Mg2TiO4 and (considering twins)(parallel)[010](001)Mg2TiO4. The film morphology is characterized by growth spirals originating from screw dislocations.
