Abstract
YFe1−xCoxO3 (0.1 ≤ x ≤ 0.5) perovskite-type nanomaterials were successfully synthesized by the chemical co-precipitation method via the hydrolysis of Y(III), Fe(III) and Co(II) cations in boiling water using 5 % aqueous KOH solution as a precipitating agent. Along with the increase of cobalt ion concentration (x values, from 0.1 to 0,5), there was an decrease in the crystallite size nanomaterials (from 25.68 to 22.89 nm), as well as in the lattice constants (a = 5.5781 – 5.5217 ˚A; b = 5.2732 – 5.2177 ˚A, c = 7.5902 – 7.5009 ˚A; V = 223.26 – 216.11 ˚A), but there was an increase in the magnetic parameters including coercive force (Hc = 88.86 Oe), remnant magnetization (Mr = 0.031 – 0.268 emu/g), saturation magnetization (Ms = 0.413 – 1.006 emu/g) and maximum energy product ((BH)max = 0.413 – 1.006 emu/g).
