ABSTRACT
Vicinal Hg[sub 1-x] Re[sub x] Ba[sub 2]CaCu[sub 2]O[sub 6+δ] films have been grown on tilted (001)SrTiO[sub 3] substrates. The c axis of films is oriented in parallel to the c axis of the substrate for tilt angles up to 12°. The vicinal films show a step-like surface morphology with smooth terraces that are tilted with respect to the substrate surface. The in-plane and out-of-plane resistivities ρ[sub ab] and ρ[sub c] reveal metallic behavior with a slight upturn near T[sub c] for the latter. The resistivity anisotropy derived from these measurements is ρ[sub c]/ρ[sub ab]∼650±150 at 300 K. This value is between that found for YBa[sub 2]Cu[sub 3]O[sub 7-δ] and the Bi-based cuprates, and it increases with decreasing temperature. © 2000 American Institute of Physics.
