Abstract
The family of the CuxNi1-x (pc) I alloys are new quasi-one-dimensional conductors that incorporate in their structure a dense array of local moments(Cu+2, S = 1/2) interacting with free carriers. The microwave conductivity (17 GHz) of these compounds being metallic at room temperature suddenly drops and shows a large positive magneto conductivity at low temperatures. The results on the alloys clearly indicate that the rapid decrease of the conductivity is closely related to the presence of the Cu+2 local moments. Al1 these observations may possibly be consistent with a one-dimensional Kondo system.
