摘要：

The influence of oxygen isotope substitution on the critical temperature T-c in La(2-y)Sr(y)Cu(1-x)Me(x)O(4) (Me=Fe, Ni) optimally doped (y=0.15) and overdoped (y=0.20) with Sr has been studied over wide range of 3d elements concentration. A substantionally different behavior of isotope exponent alpha(O) = - d(lnT(c))/d(lnM) has been found in optimally doped and overdoped compounds. A qualitative explanation is suggested for this distinction which is grounded on the specific properties of the spin correlations in LSCO.
