Abstract
We report electron heating measurements below the resistance maximum associated with the spin-glass freezing transition. The differential resistance showed features under the application of a dc electric field which cannot be readily interpreted in a simple electron heating picture. We demonstrate that these anomalies are resolved after computation of the resistance by integration of the differential results at various currents. An experiment was designed and carried out to test this procedure through the use of an applied magnetic field. The integration process is applicable to transport measurements carried out under combinations of ac and dc electric fields.
