- Abstract
- We study the structural, magnetic, and optical properties of double manganites LnBaMn2O6 with Ln = Pr, Nd, Sm, Nd1 – xSmx (x = 0.25, 0.5, 0.75). Analysis of the temperature dependences of transmission in the near IR range has shown the difference in the responses of the charge subsystem for different types of charge/orbital ordering in the system. In PrBaMn2O6 manganite, the orbital ordering of the dx2−y2 type leads to an insulator state at low temperatures. The charge subsystem of manganites NdBaMn2O6, Nd0.75Sm0.25BaMn2O6, and Nd0.5Sm0.5BaMn2O6 is sensitive to the orbital ordering type: in the temperature interval TCO2 < T < TCO1, where pairwise alignment of layers with d3x2−r2/d3y2−r2 ordered orbitals is realized, the semiconductor character of charge carriers is observed, while upon a transition to the layer-by-layer alignment of orbitally ordered layers for T < TCO2, charge carriers are of the metal character. In manganites Nd0.25Sm0.75BaMn2O6 and SmBaMn2O6, the absence of clearly manifested metal nature of the charge subsystem at T < TCO2 is associated with the formation of the antiferromagnetic ordering of the CE type.
