摘要：

Electric properties. such as electrical conductivity and thermoelectric power studies of Ni-Cd ferrites of various compositions. were investigated at room temperature. The Seebeck coefficient is negative for all the ferrites, showing that these ferrites behave as n-type semiconductors. On the basis of these results, an explanation for the conduction mechanism in Ni-Cd mixed ferrites is suggested. (C) 2003 Elsevier Science B.V. All rights reserved.
