Physical Properties of Film Alloys Based on Ferromagnetic and Noble Metals (review). ІІ. Film Materials Based on Co and Ag or Au

摘要

The results of analysis of literature and own results on the phase composition, electrophysical andudmagnetoresistive properties of film based granular alloys Co and Ag or Au. As between film systems basedudon Fe and Ag or Au and Co and Ag or Au much in common, then this work can be seen as a continuation ofud[1], although we observed significant withdrawal of these two groups of film materials in structural-phaseudstate, causing some change in electrophysical and magnetoresistive properties. The increase of the value ofudtemperature coefficient resistance film Ag (Co) at the сСо ≥ 26 at.% and the strain coefficient at theudсСо ≌ 70 at.%. It is concluded that the value of GMR completely determined by the temperatureudmeasurement and perfection of granulate state.
