Abstract
We have measured universal conductance fluctuations in the metallic spin glass as a function of temperature and magnetic field. From this measurement, we can access the phase coherence time of the electrons in the spin glass. We show that this phase coherence time increases with both the inverse of the temperature and the magnetic field. From this, we deduce that decoherence mechanisms are still active even deep in the spin glass phase.
