The magnetic and transport properties of Cr67Fe23Mn10 and Cr55Fe25Mn20 alloys

The dc magnetization, the electrical resistivity and the thermal conductivity have been measured in the temperature range of 5–300 K for Cr67Fe23Mn10 and Cr55Fe25Mn20 alloys. Curie temperature was confirmed and the ferromagnetic phase is not long-range order; Néel temperature was recorded and the antiferromagnetic phase is of spin-density wave (SDW). Our results are discussed on the basis of the magnetic nesting associated with paramagnetic and ferromagnetic cluster and SDW antiferromagnetic in this system.
