Ferrites LaNaMnFeO5 and LaKMnFeO5 have been synthesized by the ceramic method from lanthanum(III) and iron(III) oxides and sodium and potassium carbonates. The ferrites crystallize in the orthorhombic crystal system with the following lattice parameters: LaNaMnFeO5: a = 10.943 ± 0.002 Å, b = 11.022 ± 0.001 Å, c = 16.165 ± 0.028 Å, V 0 = 1949.72 Å3, Z = 16, V unit cell 0 = 12.1.85 Å3, ρX = 4.83, ρpycn = 4.76 ± 0.09 g/cm3; LaKMnFeO5: a = 10.959 ± 0.011 Å, b = 11.036 ± 0.005 Å, c = 17.825 ± 0.074 Å, V 0 = 2155.81 Å3, Z = 16, V unit cell 0 = 134.74 Å3, ρX = 4.54, ρpycn = 4.46 ± 0.07 g/cm3.
