文摘

Cuprate manganites of the composition LaM 2b> II CuMnO6b> (MII = Mg, Ca, Sr, Ba) were synthesized from lanthanum, copper(II), and manganese(III) oxides and alkaline-earth metal carbonates by high-temperature solid-phase synthesis. By grinding the produced substances in a ball mill, their nanostructured particles were obtained, the sizes of which were determined with an electron microscope. Indexing the X-ray powder diffraction patterns of the cuprate manganites established that all of them crystallize in the cubic system with the following unit cell parameters: LaMg2b>CuMnO6b>: a = 15.523 ± 0.033 ?, Z = 6, V 0 = 3740.48 ± 0.10 ?3, V el.cellb> 0 = 623.41 ± 0.03?3, ρX-rayb> = 5.81 g/cm3, and ρpycnb> = 5.75 ± 0.06 g/cm3; LaCa2b>CuMnO6b>: a = 15.422 ± 0.058 ?, Z = 4, V 0 = 3667.94 ± 0.174 ?3, V el.cellb> 0 = 916.48 ± 0.04 ?3, ρX-rayb> = 3.77 g/cm3, and ρpycnb> = 3.72 ± 0.05 g/cm3; LaSr2b>CuMnO6b>: a = 15.275 ± 0.049 ?, Z = 4, V 0 = 3564.05 ± 0.27 ?3, V el.cellb> 0 = 891.01 ± 0.07 ?3, ρX-rayb> = 4.31 g/cm3, and ρpycnb> = 4.25 ± 0.05 g/cm3; and LaBa2b>CuMnO6b>: a = 15.589 ± 0.029 ?, Z = 4, V 0 = 3788.39 ± 0.09 ?3, V el.cellb> 0 = 947.10 ± 0.02 ?3, ρX-rayb> = 4.74 g/cm3, and ρpycnb> = 4.70 ± 0.05 g/cm3. The data of an IR spectroscopic study of the cuprate manganites were presented.
