Ferrites of composition ErMIFe2O5 (M I = Li, Na, K, Cs) were synthesized by a solid-phase method. The structure of the ferrites was for the first time studied by X-ray powder diffraction. Crystal systems, unit cell parameters, and X-ray and pycnometric densities were determined. For ErLiFe2O5, a = 10.510 Å, c = 14.270 Å, V= 1616.16 Å3, Z = 16, V subcell = 101.01 Å3, ρx = 6.01 g/cm3, ρpyc = 5.97 ± 0.04 g/cm3; for ErNaFe2O5, a = 10.519 Å, c = 15.510 Å, V = 1759.56 Å3, Z = 16, V subcell = 109.90 Å3, ρx = 5.77 g/cm3, ρpyc = 5.72 ± 0.08 g/cm3; for ErKFe 2O5, a = 11.050 Å, c = 15.480 Å, V = 1937.33 Å3, Z = 16, V subcell = 121.08 Å3, ρx = 5.46 g/cm3, ρpyc = 5.41 ± 0.04 g/cm3; and for ErCsFe2O5, a = 10.78 Å, c = 16.01 Å, V = 1905.37 Å3, Z = 16, V subcell = 119.09 Å3, ρx = 6.86 g/cm3, ρpyc = 6.61 ± 0.01 g/cm3. © 2010 Pleiades Publishing, Ltd.

Double ferrites ErCaFe2O5.5, ErSrFe2O 5.5, and ErBaFe2O5.5 were synthesized by solid-state reactions from erbium and iron(III) oxides and calcium, strontium, and barium carbonates. The compounds were found to crystallize in the orthorhombic system. Their unit cell parameters were determined by X-ray powder diffraction; their densities were measured. © Pleiades Publishing, Ltd., 2010.
