Abstract :
In this paper, room temperature magnetoresistance (MR) was measured in magnetic fields up to 8.2 kOe in the current in plane configuration (CIP). The microstructural origin of changes in the magnetic properties that resulted from the addition of silver, as probed by Mossbauer spectroscopy, has been related to the magnetoresistive behavior.
