Abstract
Magnetic pressure-temperature phase diagram of La1.4Sr1.6Mn2O7 layered manganese oxide has been studied by neutron diffraction. Three phases have been found in this compound at ambient pressure: high-temperature phase with quasi two-dimensional correlations of the magnetic moments on Mn sites and two low-temperature phases with long-range order - antiferromagnetic and ferromagnetic. Under hydrostatic pressure the antiferromagnetic phase is favoured with respect to the two-dimensional and long-range ferromagnetic phases. The magnetic phase with two-dimensional correlations is thus suppressed by the anti ferromagnetic phase with long-range order. We discuss this result in terms of the pressure-induced electron transfer and compare our conclusions with predictions given by theoretical calculations.
