Structural and magnetic properties of barium hexaferrites with Gd-Co substitution
Abstract
<p>A first examination concerning possible replacement of La by Gd in Ba-La-Co hexaferrites has been conducted. Substituted samples according to the formula Ba<sub>1-x</sub>Gd<sub>x</sub>Fe<sub>12-x</sub>Co<sub>x</sub>O<sub>19</sub> (x = 0.0, 0.1, 0.2, 0.3, 0.4) were prepared by classical ceramic route. A La-Co substituted sample with composition Ba<sub>0.8</sub>La<sub>0.2</sub>Fe<sub>11.8</sub>Co<sub>0.2</sub>O<sub>19</sub>, (x = 0.2) was also prepared for comparison. The structural and magnetic characteristics have been studied by XRD, VSM, SEM and EDX techniques. The substituted samples contain small amount of α-Fe<sub>2</sub>O<sub>3</sub> impurities and traces of CoFe<sub>2</sub>O<sub>4</sub>, Fe<sub>2</sub>GdO<sub>4</sub> and GdFeO<sub>3</sub>. The coercivity of samples with x = 0.1-0.2 is higher up to 15% than in BaFe<sub>12</sub>O<sub>19</sub>, while the saturation magnetization and remanence values are lower. The Ba<sub>0.9</sub>Gd<sub>0.1</sub>Fe<sub>11.9</sub>Co<sub>0.1</sub>O<sub>19</sub> sample (x = 0.1) presents similar values of H<sub>c</sub> and σ<sub>r</sub> to the La-Co (x = 0.2) sample Ba<sub>0.8</sub>La<sub>0.2</sub>Fe<sub>11.8</sub>Co<sub>0.2</sub>O<sub>19</sub>, demonstrating the potential for use of Gd in rare-earth substituted hexaferrite permanent magnet materials.</p>
