  Epitaxial bilayers of the high-temperature-superconductor YBa2Cu3O7-d (YBCO)
and the ferromagnetic metal La0.67Ca0.33MnO3 (LCMO) were prepared by pulsed
laser deposition on (110)-oriented SrTiO3 substrates, such that the CuO2 planes
of YBCO are perpendicular to the YBCO-LCMO interface. X-ray diffraction and
Raman scattering demonstrate complete (110) orientation of both YBCO and LCMO
overlayers. The resistivity and magnetization of the bilayer films are highly
anisotropic. The critical temperatures for superconductivity and ferromagnetism
as well as the saturation magnetization exhibit modest reductions compared to
corresponding bulk values.
