摘要：

The random conductance of a mesoscopic sample of CuMn spin glass was measured under various thermal cycling conditions. Although a random spin-dependent conductance similar to that predicted by prior theory was found, no convincing evidence was found for the chaotic dependence of the spin configuration on temperature. This negative result sets some limits on the applicability of scaling theories of the spin-glass state.
