    Abstract

    Based on high-resolution neutron diffraction data, the metal-insulator transition of Pr1/2Sr1/2MnO3 at 150 K is shown to be due to a temperature-driven structural instability (I4/mmm → P21/n) as temperature decreases. The allowed breathing-type distortions do not stabilize a charge ordered state in the A-type magnetic configuration observed in the P21/n phase.
