High pressure effect on the crystal and magnetic structure of Pr0.1Sr0.9MnO3 manganite

Original language description

The crystal and magnetic structure of Pr0.1Sr0.9MnO3 manganite has been studied by the neutron dif fraction at high pressures up to 5 GPa in the temperature range 10-295 K. At normal pressure and decreasing temperature the appearance of the C -type (TN =220 K) and G -type (TN = 180 K) antiferromagnetic states occurs, which is accompanied by a structural phase transition from the cubic structure(Pm3m space group) to the tetragonal structure (I4/mcm space group). It is shown that the temperature of the transition to the C -type antiferromagnetic phase increases with pressure with the pressure coefficient dTN/dP = 4.0(5) K/GPa and the temperature of the transition to the G -type antiferromagnetic phase weakly depends on pressure.
