摘要：

The method of determination of the pinning current density J(c) and the bulk first critical field H(c1) from the magnetization data of high T(c) superconducting single crystals is presented. The method is based on the original critical state model regarding the shape of the sample, the change of the demagnetization factor with flux penetration, real distribution of the magnetic field and equilibrium flux density within the sample. The method was applied to Tl2Ba2CaCu2O(x) single crystals.
