的ESR谱（在1.12 GHz）和自旋玻璃AgMn的磁化反转的Mn浓度为8.3原子%之间观察到的相关性。这是因为在磁化反转期间自旋系统的重排。ESR谱线W↑和W↓的宽度是不同的，它们分别与正磁化和负磁化的反转有关。这归因于在两个反转期间的有效各向异性常数K的不同值。从而得到了ESR线宽与各向异性常数之间的关系。
A correlation is observed between the ESR spectra (at 1.12 GHz) and the magnetization inversions of the spin glass AgMn for a Mn concentration of 8.3 at. %. This is because of rearrangement of the spin system during the magnetization inversions. The widths of the ESR lines W↑ und W↓ which correlate, respectively, with the reversals to positive and negative magnetization are different. This is ascribed to different values of the effective anisotropy constant K during the two reversals. Thus a relationship is obtained between the ESR linewidth and the anisotropy constant.
