Effect of high hydrostatic pressures (up to 15 kbar) on the spectrum of Andreev reflection within the MgB2/Ag contacts is carried out. As shown, the pressure leads to a decrease in the superconducting energy gap for the σ-band and to a substantial increase in the energy gap for the π-band. In this case, a significant increase in the excess current of the current–voltage characteristic of the contact is observed. A possible reason for such a response of the spectroscopic characteristics of magnesium diboride to hydrostatic compression is the pressure-induced intensive scattering of electrons by mobile edge dislocations in MgB2 crystals.

Key words: magnesium diboride, energy gaps in π- and σ-bands, high hydrostatic pressure.
