Investigations on aligned HgBa{sub 2}Ca{sub 1}Cu{sub 2}O{sub 6+{delta}} (Hg-1212) powder were performed by measuring magnetization parallel and perpendicular to the applied magnetic field as a function of temperature, field, and the field orientation in the irreversible regime. The anisotropy ratio {epsilon} {approx} 1/5 is found indicating that Hg-1212 is one of the least anisotropic materials amongst the technically important high-T{sub c} superconducting families. The scaling results for the magnetic field, the in-plane and the out-of-plane critical current densities agree precisely with the collective pinning theory and its scaling approach for anisotropic materials.
