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