โœฆ Synopsis

Bitter-pattern observations of the vortices for flux trapped at the liquid nitrogen temperature in YBa2Cu;O7 thin films with the c-axis and ( 110 ) direction parallel to the surface are reported. The penetration-depth anisotropy is estimated to be 5 from the vortex shape. The shape and distribution of the spots give a visual description of the homogeneity in the film.
