Abstract

Magnetic states of Cu1 sublattice in YBa2Cu3O y : 1%57Fe compounds with 6.09 ≤y≤6.98 were investigated by57Fe Mössbauer spectroscopy at 1.68≤T≤300 K. It has been found that, upon reducingy, the magnetic transition temperatureT ml changes from 3.3 to 12 K aroundy≃6.4 where the superconductivity disappears. The magnetic phase diagram for the Cu1 sublattice is plotted.
