抜粋

We report irreversibility fields Birr and critical current densities Jc in YBa2Cu3O7-x thin films containing segmented BaSnO3 nanorods. Birr and Jc are systematically changed by selection of nanorod length and its spacing, and the variations are explained by the "harmonic oscillator" approach based on the Bose glass state. Analysis of pinning energies and Jc indicates that segmented nanorods behave as single columnar pin for B ∥ c, in contrast, as nanoparticle pins for B ∥ ab. The present results may help to further investigate anisotropy tuning of pinning structures.
