测量了Fe_（91.4）Ga_（8.6）、Fe_（83.4）Ga_（16.6）和Fe_（71.5）Ga_（28.5）的最低阶磁各向异性常数K~（-1）和最低阶饱和磁致伸缩常数（3/2）λ（100）的温度依赖性，并与归一化磁化强度幂律m（1（1 + 1）/2）进行了比较。Fe_（91.4）Ga_（8.6）保持了Fe（d λ（100）/dT> 0）和K的磁致伸缩异常，符合m（l（l +1）/2）幂律，K-1（0K）等于90kJ/m（3）。Fe_（83.4）Ga_（16.6）没有表现出磁致伸缩异常，但非常好地符合幂律。Fe_（71.5）Ga_（28.5）在所有温度下都具有小的K~（-1）（近似于1 kJ/m（3））和大的温度依赖性磁致伸缩，在低温下达到近似于800 ppm。(c)2005年美国物理学会。
The temperature dependence of the lowest order magnetic anisotropy constant K-1 and the lowest order saturation magnetostriction constant, (3/2)lambda(100), were measured from 4 K to 300 K for Fe91.4Ga8.6,Fe83.4Ga16.6, and Fe71.5Ga28.5 and were compared to the normalized magnetization power law, m(l(l+1)/2). Fe91.4Ga8.6 maintains the magnetostriction anomaly of Fe (d lambda(100)/dT > 0) and K, is a reasonable fit to the m(l(l+1)/2) power law with K-1(0 K) congruent to 90 kJ/m(3). Fe83.4Ga16.6 does not show a magnetostriction anomaly, but fits the power law remarkably well. Fe71.5Ga28.5 possesses a small K-1(similar to 1 kJ/m(3)) at all temperatures and a large temperature dependent magnetostriction, reaching similar to 800 ppm at low temperature.
