✦ Synopsis

The effects of pressure on the temperature of the superconductive transition and the critical field of irreversibility for n-type polycrystalline high-To compounds Ln2_~lxCuO4_y (Ln=Nd, Sin, Pr, M=Ce, Th) was investigated. The pressure derivatives of critical parameters are less in magnitude than these for p-type high-To compounds. This fact may be accounted for by structure peculiarities of electron-doped HTSC.
