ELECTRICAL-RESISTIVITY OF DYCO3B2 COMPOUND

New results of the transport and electronic properties of DyCo3B2 comp ound are reported. This compound crystallizes in the hexagonal CeCo3B2 type structure. The resistivity at low temperatures shows a T-2 depen dence, 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-po larised LMTO method. The calculated contribution from the band structu re to the resistivity is close to the experimental results. (C) 1998 E lsevier Science B.V. All rights reserved.
