| dc.description | High precision data for the electrical resistance of dysprosium in the region of the Neel point have been obtained using the direct current comparator method. Results are given for both b- and c-axis samples cut from the same high quality monocrystal. In the immediate vicinity of the Neel point (BT-T<sub>N</sub> mod <or=2.5K), the c-axis resistance, R<sub>c</sub>, cannot be convincingly described by a power law. Reasons for this are discussed. However, R<sub>c</sub> is described by a power law for 2.5<or=T-T<sub>N</sub><or=60K and for -15<or approximately=T-T<sub>N</sub><or approximately=-2.5K with exponents psi <sub>+</sub>=0.60 and psi <sub>-</sub> approximately=1.25 respectively. In the case of b-axis data, R<sub>b</sub> is linearly dependent on T for T>or=T<sub>N</sub>, whereas a power law, of weak amplitude but with psi <sub>-</sub> approximately=1.25, is valid below T<sub>N</sub>. The results suggest that dR/dT varies as the magnetic specific heat below T<sub>N</sub> for both the b- and c-axis resistance. |
