Abstract—Manganite ferrites (M^II = Mg, Ca, Sr, Ba) were synthesized from neody-
mium(III), manganese(III), and iron(III) oxides and alkaline-earth metal carbonates by a ceramic technology.
By grinding the obtained compounds in a ball mill, their nanostructured particles were produced, the sizes of
which were determined with an electron microscope. X-ray diffraction study established that the nanostructured
compounds crystallize in the cubic and tetragonal systems with the following lattice parameters:
NdMg_1.5MnFeO₆ (tetragonal): a = 10.955 Å, c = 17.848 Å, V⁰ = 2141.975 ų, Z = 16, = 133.873ų, _X-
ray = 4.80 g/cm³, and _pycn = 4.76 0.05 g/cm³; NdCa_1.5MnFeO₆ (cubic): a= 10.809 Å, V⁰ = 1262.864 ų, Z =
8, = 157.858 ų, _X-ray = 4.32 g/cm³, and _pycn = 4.27 0.03 g/cm³; NdSr_1.5MnFeO₆ (cubic): a = 10.911
Å, V⁰ = 1298.953 ų, Z = 8, = 162.369 ų, _X-ray = 4.93 g/cm³, and _pycn= 4.88 0.05 g/cm³; and
NdBa_1.5MnFeO₆ (tetragonal): a = 11.011 Å, c = 18.001 Å, V₀ = 2182.479 ų, Z = 16, = 136.405 ų, _X-
ray = 6.78 g/cm³, and _pycn= 6.75 0.07 g/cm³.
