Transverse and longitudinal magnetostriction was measured in ceramic YBa2Cu3O7−δ and Hg0.8Pb0.2Ba2Ca2Cu3O8+δ superconductors by the strain gauge technique. The measurements were performed in an external magnetic field up to 12 T. The observed magnetostriction was shown to consist of two components. The first one is connected with the intragrain — and the second one with the intergrain screening currents. Both components of the magnetostriction were analyzed independently in frames of an isotropic theory of the pinning induced magnetostriction.
