The thermotransport of 54Mn in pure or Mn-doped crystals was determined, at temperatures ranging from 954 to 1040K, by means of Soret-effect measurements. The mean value of the impurity heat of transport was found to be equal to -206kJ/mol for pure crystals and equal to -166kJ/mol for doped crystals.
