Abstract

The electrical resistivity, thermal conductivity and low-frequency internal friction of Cr 75 (Fe x Mn 1− x ) 25 ( x =0.64, 0.72) alloys are studied in the temperature range 77–300 K. The initial increase in the resistivity and the decrease in the thermal conductivity as temperature decreases below T N are attributed to the progressive opening of the energy gap related to the antiferromagnetic transition in the alloys. The energy gap is estimated and the lower limit of value 2Δ( T C )/ k B T C is 1.13 and 1.30 for Cr 75 (Fe x Mn 1− x ) 25 of x =0.64 and 0.72, respectively.
