“…Previous works [1][2][3][4] describe how the vortex flux pinning by the lattice is clearly shown from magnetostriction measurements at the superconducting regime, as we believe to have observed in the present 2H-NbSe 2 also. First of all and most important is the already mentioned strong hysteresis shown by the λ(c, a) and λ(a, a) modes, similar to the magnetization hysteresis, which is assigned to pinning effects.…”

“…In this way the models [7,9] yield scaling law F p (H) ∼ f(h), and predict a (H * (T)) 2.5 dependence for F p . Thus one should expect for the flux-pinning magnetostriction the scaling behavior followed by F p (see (1)), if the field dependence of elastic constants is not taken into account. This approach perfectly describes the results obtained on the high-T c superconductors [1].…”

“…The recent magnetostriction measurements performed in the mixed state of superconductors, the so-called Shubnikov phase has proved to be the alternative tool for studying interplay between the Abrikosov flux line lattice (FLL) and crystal lattice [1][2][3][4]. Though unambiguous manifestation of pinning phenomena in the irreversible magnetostriction was obtained some questions are still open.…”

Peak and oscillations in the measured field dependences of magnetostriction were observed near H c2 . The reversible and irreversible components are separated and analyzed in the region of peak. The scaling parameters are defined, the contribution of the elastic constants dependence on magnetic field is demonstrated. The oscillatory component is discussed regarding Landau quantization of electronic spectrum.

“…Measurements of the irreversible «giant» magnetostriction in HTSC [1][2][3][4] appears to be an effective tool for examination of the pinning-related phenomena in hard superconductors. The 1D case was considered in detail for a thin long strip in a longitudinal magnetic field [5], and good agreement was achieved with the conventional models [6][7][8][9] of the magnetic flux distributions in type-II superconductors.…”

A .Investig ation of magnetic flux g rad i e nts in har d super con duct ors Analytical calculations of the transverse magnetostriction in a thin hard superconductor are presented in relation to the distributions of currents and fields within a superconducting specimen in a varied magnetic field. The approach is successfully tested on high-temperature superconductors. The flux distribution derived from magnetostriction measurements is in satisfactory agreement with that obtained from computer processing of magnetooptical images. The magnetic flux distribution below the irreversibility line of hard superconductors is derived from both original magnetization and magnetostriction measurements and image processing. Perfect consistency of the results is obtained for a family of high-temperature superconductors
