Abstract

The charge and orbital ordered states in the single-layered manganite crystals, Nd_1-xSr_1-xMnO₄ (x = 0.67, 0.75), have been investigated. We have observed the superlattice spots with modulation wave vector, q = (δ, δ, 0), δ = 1/8, 1/4 [∼1/6,1/3] in x = 0.75[0.67] by resonant and non-resonant X-ray scattering. These results show that not only the atomic displacement pattern but also the charge-orbital structure has the unit cell of 4√2a × √2a × c [3√2a × √2a × c].
