Sažetak
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 ( ) in the corresponding temperature interval have been used. The values deduced from RH (χ ) plots are about ­2×10­10‏ ‏ ‏ ‏ ‏ ‪ ‫ ‬ m3C­1 for R0, and about 5×10­7 m3C­1 for RS. When the possible dependence of RS on temperature, that is due to the temperature dependence of the electrical resistivity  (T), is taken into account the values are about zero for R0, and about 3×10­7 m3C­1 for RS (295 K). No significant composition dependence of R0 has been detected.
