Abstract

We examine the transverse magnetoresistance of three-dimensional bi-component composites Au_p-(PrBa₂Cu₃O ₇)_1-p. This property, seldom measured on percolation systems, has been measured below 5K and up to 1.5T. Contrarily to well known transport properties, the magnetoresistance of these compounds exhibits a metal volume fraction's threshold p_c linked to the onset of disorder rather than to percolation.
