The Research of Spin-Orbital Interaction in Intermetallic Compounds of System Gd-In on Paramagnetic Area

Normal, R0, and anomalous, RS, 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 SO of intermetallic compounds are calculated from anomalous components RS of the Hall coefficient and specific electrical resistance. The results calculated for the band parameters and effective parameters of spin-orbital interaction 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).
