Electrical noise in the spin-glass AuFe
… AuFe in order to compare with prior results in CuMn. Macroscopic AuFe samples showed a sharp increase in the noise with the onset of the noise at a temperature corresponding to the peak in the magnetic susceptibility as a function of temperature. This temperature is identified as the transition …

Electrical noise study of spin glass dynamics in mesocopic CuMn
… resistance of the archetypal spin glass CuMn is surprisingly sensitive to small changes in the spin configuration. This enhanced sensitivity results from long-range electron quantum interference at low temperatures. Due to this effect, substantial resistance noise is produced by …
