摘要:
We report on results of resistivity and Hall effect measurements performed on a CeFe2Si2 single crystal. The resistivity, studied in the temperature range from 2-300 K and in the magnetic fields up to 12 T, was found to be field independent, showing no anomaly and no pronounced anisotropy between a- and c-axis in the temperature dependence. The Hall coefficient increases monotonously with increasing temperature. The normal Hall constant at 2 K is R-H = 3.26 x 10(-9) m(3)/C. The susceptibility of the compound is of the order 10(-8) mol m(-3) and decreases with the increasing temperature. (c) 2005 Elsevier B.V. All rights reserved.
