Query: Scaling laws for the critical current density in anisotropic biaxial
  superconductors   To understand the anisotropy of flux pinning and critical current density in
technological superconductors, the scaling law for the anisotropy of
single-vortex collective pinning in uniaxial superconductors is extended to
flux-bundle collective pinning in biaxial superconductors. The scaling results
show that in a system of random uncorrected point defects, the critical current
density is described by a unified function with the magnetic field of the
scaled isotropic superconductor. The obtained angular dependence of the
critical current density depicts the main features of experimental
observations, considering possible corrections due to the strong-pinning
interaction.
