摘要
The unit cell parameters of the crystal structures of the ferrocuprate solid solutions Sm1/2Gd1/2BaCuFeO5.05, Gd1/2Yb1/2BaCuFeO5.02, and Ho1/3Yb2/3BaCuFeO5.05 in air in the temperature range 293-1093 K have been determined by X-ray powder diffraction, and their electrical conductivity has been studied. The structural characteristics of layered ferrocuprates are determined by the size of rare-earth cations in their structures, whereas the conductivity of ferrocuprates depends on the electronic configuration of these cations.
