发现 3d 自旋玻璃磁化率的静态和动态缩放可产生一致的结果，并且意味着在有限温度下存在零场相变。另一方面，场内行为的动态尺度分析表明，在施加的磁场中不存在相变。讨论了在响应函数和场冷却磁化强度中观察到的自旋玻璃的老化现象，并得出了其与基础自旋构型之间关系的唯象图。
Static and dynamic scaling of the susceptibility of 3d spin glasses is found to yield consistent results and imply that there is a zero field phase transition at a finite temperature. On the other hand, dynamic scaling analysis of the in-field behaviour suggests that there is no phase transition in an applied magnetic field. The ageing phenomenon in spin glasses as observed in the response function and the field cooled magnetisation is discussed and a phenomenological picture for how it relates to the underlying spin configuration is derived.
