Abstract
The thermoelectric power of two crystals of AgCl doped with Mn2+ ions has been measured over a range of temperatures from 97 to 414 degrees C using Ag electrodes. These data, and also earlier data for pure AgCl and for AgCl doped with Cd2+ ions have been shown to be fully consistent with the assumption that the heats of transport, and also another related parameter, are independent of temperature. The value of the heat transport for Ag+ ions migrating on the cation sublattice by a vacancy mechanism (QM) is 0.311 eV, while the values for the collinear (Qic) and noncollinear (Qinc) mechanisms are -0.180 eV and -1.20 eV respectively. These numerical values are consistent with elementary theories of the heat of transport.
