The concentration dependence of magnetic properties of iron alloys with 3–25% of gallium is studied. It was shown that the saturation induction monotonically decreases with increasing gallium content, while the coercivity exhibits a step increase with a step from 85 to 135 A/m between 12 and 15 at % Ga. The effect of magnetic field annealing (MFA) on the behavior of the residual induction and coercive force in alloy samples containing from 3 to 18 at % Ga is studied. As a result of MFA, magnetic anisotropy is induced in the alloy: magnetic hysteresis loops become narrower, the residual induction increases, and the coercivity decreases. The MFA efficiency reaches a maximum at a Ga content of 15–18 at %. The features of the structure state of iron–gallium alloys and their role in the formation of magnetic properties during annealing in a dc magnetic field are discussed.

磁场退火对铁镓合金磁性能的影响

研究了镓含量为3–25％的铁合金的磁性的浓度依赖性。结果表明，随着镓含量的增加，饱和感应强度单调降低，而矫顽力则在12至15 at％Ga之间以85 A / m至135 A / m的阶跃增加。磁场退火（MFA）对金属的影响研究了Ga含量为3至18 at％的合金样品中残余感应力和矫顽力的行为。MFA的结果是，合金中产生了磁各向异性：磁滞回线变窄，残余磁感应强度增加，矫顽力降低。当Ga含量为15–18 at％时，MFA效率达到最大值。
