Abstract
Signatures of spin-glass freezing such as the appearance of 1/f conduc tance noise, the recovery of universal conductance fluctuations, aging , as well as magnetic and thermal irreversibilities, are detected in m esoscopic wires of Cd1-xMnxTe:I at millikelvin temperatures. Spectral characteristics of conductance time series are consistent with the dro plet model of short-range spin glasses.
