Abstract

Bulk mechanical alloying was used to fabricate the supersaturated solid solution of Cu80Co20. The nano-Co particulates Cu-matrix alloy was made by low-temperature annealing. Both the annealing temperature and time were parametrically varied to describe the relationship between process condition and magnetic properties. The maximum magnetoresistance ratio under 1.0 MA/m at room temperature of 4.9% was measured for this nano-particulate material with the mean Co-particulate size of 6 nm. From the measured magnetic properties, the effect of particulate size of Co in Cu-matrix on the magnetic properties was discussed.
