Magnetic and magnetodielectric properties of Y3−xLaxFe5O12 ceramics

Y3−xLaxFe5O12 (x = 0–0.5) ceramics with garnet structure are prepared by the solid state reaction method and their structural, magnetic, and magnetodielectric properties are investigated systematically. La3+ substitution leads to lattice expansion and possible ion transposition, which oppositely affect the variation of Fe2+ concentration. As a result, both the saturation magnetization and the intrinsic magnetodielectric effect first increase and then decrease with the increase of La concentration. More interestingly, room temperature large magnetodielectric coefficient of about −5% is obtained at 106 Hz and 0.9 T for Y2.7La0.3Fe5O12 ceramics. This study provides a feasible alternative method for modulating the saturation magnetization and the magnetodielectric effect of Y3Fe5O12-based materials.
