Normal, R₀, and anomalous, R_S, components of the Hall coefficient are determined from the results of experimental investigations of temperature dependences of the Hall coefficient, magnetic susceptibility, and specific electrical resistance for intermetallic Gd₃In, Gd₃In₅ and GdIn₃ compounds. Effective parameters of spin-orbital interaction λ_SO of intermetallic compounds are calculated from anomalous components R_S of the Hall coefficient and specific electrical resistance. The results calculated for the band parameters and effective parameters of spin-orbital interaction λ_SO for Gd-In system intermetallides coincide by orders of magnitude with the results obtained from the optical spectra of pure REMs (rare-earth metals).
