The influence of the order-disorder structural transition on the transport properties of Fe-rich B2-phase Fe_(0.52)Al_(0.48) alloy films has been investigated. The disordered alloy film was obtained by vapor-quenching deposition onto glass substrates cooled by liquid nitrogen. The electric resistance of the ordered and disordered Fe_(0.52)Al_(0.48) alloy films have been measured in the 5-300 K temperature range in the presence and absence of a magnetic field of 0.5 T. The influence of the order-disorder structural transition on the location of the resistance minimum at low temperature was analyzed within the framework of the "variable-range-hopping conductivity" approach.
