| 中文摘要 | 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 charge-and orbital-ordered (CO/OO) near T-co = 300 K and then develops checkerboard-like antiferromagnetic (AF) order below T-N = 130 K. At temperatures above T-N but below T-co (T-N < T < T-co), the appearance of short-range AF spin correlations suppresses the CO/OO-induced orthorhombic strain, contrasting with other half-doped manganites, where AF order has no observable effect on the lattice distortion. These results suggest that a strong spin-lattice coupling and the competition between AF exchange and CO/OO ordering ultimately determines the low-temperature properties of the system. |
