摘要：

We demonstrate that an A-type antiferromagnetic (AFM) state of Pr0.5Sr0.5MnO3 exhibits a charge ordering that governs the transport property. This charge ordering is stripelike, being characterized by a wave vector qsimilar to(0,0,0.3) with very anisotropic correlation parallel and perpendicular to the stripe direction. This charge ordering is specific to the manganites with relatively wide one-electron bandwidth W which often exhibit a metallic A-type AFM state, and should be strictly distinguished from the CE-type checkerboardlike charge ordering commonly observed in manganites with narrower W, such as La1-xCaxMnO3 and Pr1-xCaxMnO3.
