The effect of magnetic field on thermopower of CeFe2
2004
Abstract The thermopower of MgCu 2 -type C15 Laves phase compound CeFe 2 have been measured in the temperature range from 1.5 to 300 K under magnetic fields up to 15 T . Temperature dependence of S shows no distinct anomaly at T C in zero magnetic field and also in magnetic field. S is positive except low temperature. At low temperatures, S ( T ) curves are represented by S ( T )= aT + bT 3/2 , where the coefficient of a shows no field dependence, on the other hand, b decreases with increasing magnetic field. It implies that the antiferromagnetic fluctuations have an important role at low temperatures.
