摘要：

New results of the transport and electronic properties of DyCo3B2 compound are reported. This compound crystallizes in the hexagonal CeCo3B2 type structure. The resistivity at low temperatures shows a T-2 dependence, implying that the electron-spin wave scattering is dominant in this temperature range. The experimental results are discussed on the basis of s-d scattering in the high temperature range. The electronic structure of DyCo3B2 compound is calculated by self-consistent spin-polarised LMTO method. The calculated contribution from the band structure to the resistivity is close to the experimental results. (C) 1998 Elsevier Science B.V. All rights reserved.
