| dc.description.abstract | Electrical resistivi~ measurements have been made on Ni, Ni-5 at% Co,
Ni-5 at% V, Ni-5 at% Pt and Ni-5 at% Al in the temperature range
from 20 °c to at least 70 °c above the Curie temperatures of the
alloys. For T > Tc the temperature coefficients of resistivity of
Ni as well as of the ~Co and NiPt alloys showed a logarithmic divergence
whereas the NiV and NiAl alloys showed no such logarithmic
divergence. For T < Tc none of the resistivity coefficients showed
a logaritmic divergence. The additional resistivity caused by
alloying Ni with the different solutes shows a quadratic relationship
(of the same kind as Linde~s rule) to a quantity which may be
interpreted as the effective valence difference between the solvent
(Ni) and the solute | en |
