Abstract
The structural changes associated with the ferromagnetic (FM) metallic-to-antiferromagnetic (AFM) insulating transition of Pr1/2Sr1/2MnO3 (I4/mcm→P21/n) have been analyzed by means of high-resolution neutron diffraction data. Mn positions in the low-temperature phase have the same charge and identically deformed octahedra. The transition is the result of a stretching-like distortion of the octahedra that (i) contracts the Mn-O bond perpendicular to the FM planes by deviating β from 90 °C and (ii) injects electrons into in-plane Mn-O bonds.
