Time-dependent thermoremanent magnetization (TRM) studies have been instrumental in probing energy dynamics within the spin glass phase. In this paper, we review the evolution of the TRM experiment over the last half century and discuss some aspects

Using high resolution superconducting quantum interference device magnetometry we have made detailed measurements of the waiting time effect of the thermoremanent magnetization (TRM) decays on a single-crystal $\mathrm{Cu}\mathrm{Mn}(6%)$ spin-glass

The growth of the spin-glass correlation length has been measured as a function of the waiting time $t_{\mathrm{w}}$ on a single crystal of CuMn (6 at.\%), reaching values $\xi\sim 150$ nm, larger than any other glassy correlation-length measured to

Thin-film multilayered spin-glass CuMn/Cu structures display glassy dynamics. The freezing temperature ${T}_{f}$ was measured for 40 layers of CuMn films of thickness $\mathcal{L}=4.5,9.0$, and 20.0 nm, sandwiched between nonmagnetic Cu layers of thi

The mesoscale allows a new probe of spin glass dynamics. Because the spin glass lower critical dimension ${d}_{l}g2$, the growth of the correlation length $\ensuremath{\xi}(t,T)$ can change the nature of the spin glass state at a crossover time ${t}_

We report the effect of varying cobalt thickness on the temperature-dependent time decay of the electrical resistance of Co/Sb multilayer samples. We find that for a given temperature, a five fold change in the Co thickness produces a 100 fold change

We have developed a thermally activated Time-Temperature Indicator (TTI) suitable for use in passive and active RFID applications. In general, this type of indicator can be used in the cold chain to monitor the thermal age of foods and pharmaceutical
