Title: Effect of antiferromagnetic spin correlations on lattice distortion and charge ordering in Pr0.5Ca1.5MnO4

Abstract

We use neutron scattering to study the lattice and magnetic structure of the layered half-doped manganite Pr0.5Ca1.5MnO4. On cooling from high temperature, the system first becomes chargeand orbital-ordered (CO/OO) near TCO = 300 K and then develops checkerboard-like antiferromagnetic (AF) order below TN = 130 K. At temperatures above TN but below TCO (TN
