Abstract
- The regulation of Fe<superscript>2+</superscript> in yttrium iron garnet is a crucial factor in determining its dielectric and magnetic properties. This study successfully prepared Y<subscript>3</subscript>Mn<subscript>0.2</subscript>Fe<subscript>4.8</subscript>O<subscript>12</subscript> ceramics, and studied their microstructure, magnetism, dielectric properties, and ferromagnetic linewidth through Mn<superscript>n+</superscript> ion doping. The microstructural analysis revealed that the doping of low-valence Mn led to an increase in the grain size and density of ceramics, while the Mn<superscript>4+</superscript>–YIG showed the emergence of the second phase of YFeO<subscript>3</subscript>. Chemical composition analysis confirmed that the Fe<superscript>2+</superscript> content was regulated by the Mn valence and that the lowest value was observed in Mn<superscript>2+</superscript>–YIG. The hysteresis loop demonstrated that the saturation magnetization decreased with the increase of Mn valence. In addition, low-valence Mn doping also reduced the dielectric loss and ferromagnetic resonance linewidth. Therefore, this study confirmed that low-valence metal doping could be a promising approach for regulating the Fe<superscript>2+</superscript> content in YIG. [ABSTRACT FROM AUTHOR]
