Abstract

The technology for preparation of Ho_5Sb_3 thin films was developed. The samples were prepared by vacuum thermal evaporation from two independent sources of Ho and Sb. Films had a hexagonal lattice with parameters a = 8.85 and c = 6.24 Å. Temperature dependence of the specific resistivity, Hall constant and thermo-EMF coefficient of these samples were measured in the temperature interval from 100 to 700 K. Based on these measurements the basic electro-physical parameters carriers mobility and concentration were determined in the one-band approximation. Obtained results reveal that Nd_5Sb_3 is a semi-metallic compound.
