New Phase Transition in the $Pr_{1-x}Ca_{x}MnO_{3}$ System: Evidence for Electrical Polarization in Charge Ordered Manganites

In this Letter a detailed study of the electric field gradient (EFG) across the Pr1-xCaxMnO3 phase diagram and its temperature dependence is given. Clearly, distinct EFG behavior for samples outside or inside the charge order (CO) region are observed. The EFG temperature dependence evidences a new p...
