Electrical resistivity measurements in cobalt and dilute cobalt alloys following low-temperature electron irradiation

Abstract

The recovery of the electrical resistivity is reported for low-temperature electron-irradiated cobalt and dilute Co–Si and Co–C alloys. Samples have been irradiated to a range of doses extending from 0·25 × 10 to 24·5 × 10²² m⁻². A large stage I recovery (up to 78%) with a number of substages has been observed. One of these substages (I_D2 at 53 K) is influenced by both irradiation dose and the impurity level; this stage can be attributed to correlated recovery. No evidence for a dose-dependent substage I_E is observed. The influence of silicon and carbon on the recovery is discussed.
