Cross-sectional TEM images of YBCO/BZO films grown at (a) and (b) . Examples of path followed by the BZO nanorods are marked by lines in the lower half of the figures. The scale bar represents 50 nm in both images. Note that both images were recorded at the same magnification, but some damage during TEM sample preparation makes the film in Fig. 1(b) appear thinner.
as function of applied magnetic field for two groups of YBCO/BZO grown at 790 (Low group) and (High group) at 77 K. Solid symbols are designated to Low group while open ones to High group. A curve of a standard thick film is also included for comparison.
as function of , which is the angle enclosed between applied magnetic field and film normal for two representative thick YBCO/BZO films from low group and high group. A similar curve measured on a thick standard YBCO film is also plotted together.
curves of low (solid symbols) and high group (open symbols) at 77 K and various magnetic fields.
(a) curves of YBCO/BZO films (solid symbols) from low group and standard YBCO film (dash line) at various reduced temperature and SF. Solid lines are drawn to guide eyes; (b) of a YBCO/BZO sample from low T group and a standard YBCO film. Both films have thickness of .
