Using pulsed laser deposition, YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] (YBCO) films ranging in thickness from 0.065 to 6.4 [mu]m have been deposited on yttria-stabilized zirconia substrates with an intermediate layer of CeO[sub 2]. The thinnest films have critical current densities of over 5 MA/cm[sup 2] at 75 K with zero applied field; as film thickness is increased, [ital J][sub [ital c]] decreases asymptotically to 1 MA/cm[sup 2]. X-ray analysis of a 2.2-[mu]m-thick film shows that the YBCO is predominantly [ital c]-axis oriented and textured in-plane, while a Rutherford backscattering spectrometry minimum channeling yield of [approx]75% indicates that the film contains disordered material at this thickness.
