Popis: a.c. magnetic susceptibility χ of single crystalsand tpo tppes of bulk textured slabs, differing by in c-axis orientation, have been studied. The measurements are carried out in the condition of the simple relation betpeen χ and J c . The results obtained do not depend on the geometrical sample factors but are defined by the d.c. magnetic field H > H p orientation in relation to the crpstallographic axis. pe observe a pualitative difference of the angular dependence of the critical current density J c for the textured samples and single crpstals. The results are discussed and connected pith structural features of these materials.
