The Hall coefficient (RH) of Al73Mn27–xFex (x = 0, 2, 4 and 6) complex metallic alloys has been measured in the temperature interval from 90 to 400 K. All the alloys are T (Taylor) phase except Al73Mn21Fe6 that is a decagonal (d) quasicrystal. The Hall coefficients of all the samples are positive and they decrease strongly with the increase of temperature according to the Curie-Weiss [C/(Tθ)] law. Therefore, for the separation of the normal (R0) and anomalous (RS) Hall coefficients, the results for the paramagnetic susceptibility (χ) in the corresponding temperature interval have been used. The values deduced from RH(χ) plots are about –2 × 10–10 m3 C–1 for R0, and about 5 × 10–7 m3 C–1 for RS. When the possible dependence of RS on temperature, that is due to the temperature dependence of the electrical resistivity ρ(T), is taken into account the values are about zero for R0, and about 3 × 10–7 m3 C–1 for RS (295 K). No significant composition dependence of R0 has been detected.
