Investigation of the effective parameter of spin-orbital interaction in intermetallic compounds of the Tb-In system in the paramagnetic region

The normal, R₀, and anomalous, R_S, components of the Hall coefficient are determined from experimental temperature dependences of the Hall coefficient, magnetic susceptibility, and specific electrical resistance of the Tb₂In and Tb₅In₃ intermetallic compounds. The band parameters, radius of the Fermi sphere k_F, and the Fermi energy E_F of the examined samples are calculated for the known values of the normal component of the Hall coefficient R₀. Values of the anomalous component R_S of the Hall coefficient and specific electrical resistance ρ are used to calculate the effective spin-orbital interaction parameters λ_SO for the intermetallic compounds.
