复杂系统中的老化现象已被用作研究复杂性物理的重要工具。特别是，使用热剩磁衰减测量的自旋玻璃的老化效应，对于复杂平衡和非平衡动力学的探测很有帮助。在这封信中，我们表明自旋玻璃材料中发现的老化具有有限的寿命。衰减的老化部分结束后，我们发现老化后衰减本质上显然是对数的。这种衰减与等待时间无关，并且是产生老化的同一机制的一部分。
Aging phenomena in complex systems have been used as an important tool to investigate the physics of complexity. In particular, aging effects in spin glasses, measured using the thermoremanent magnetization decays, have been instrumental as a probe of complex equilibrium and nonequilibrium dynamics. In this Letter, we show that aging found in spin glass materials has a finite lifetime. After the aging part of the decay has ended, we find a post-aging decay which is apparently logarithmic in nature. This decay is independent of the waiting time and part of the same mechanism that produces aging.
