Field dependence of the thermopower of CeNiSn
  Previously measured thermopower data of CeNiSn exhibit a significant sample dependence and non-monotonous behavior in magnetic fields. In this paper we demonstrate that the measured thermopower S(T) may contain a contribution from the huge Nernst coefficient of the compound, even in moderate fields of 2 T. A correction for this effect allows to determine the intrinsic field dependence of S(T). The observed thermopower behavior can be understood from Zeeman splitting of a V-shaped pseudogap in magnetic fields.
