    Abstract

    Pr K-edge XAFS spectrum as a function of temperature in Pr 0.5Sr0.5MnO3 has been recorded on BL01B1 beam line at Spring-8, in order to study the effect of lattice distortions as the sample passes from a paramagnetic insulator phase at room temperature to ferromagnetic metal phase below 265 K and to an antiferromagnetic insulator phase at low temperatures. It is found that when the ferromagnetic to antiferromagnetic transition takes place, the MnO6 octahedra rotate in the ab-plane and tilt away from the vertical along the c-axis. The tilting of the MnO6 octahedra is responsible for the A-type antiferromagnetic phase.
