摘要：

We have determined a maximum MR of 22% in melt-spun Cu70Cu30 after annealing at 450 degrees C for 1 hr. Two types of Go-rich precipitates were found in the as-spun ribbon but these do not appear to contribute to the MR. On annealing, a very fine distribution of Go-rich precipitates forms at temperatures above 300 degrees C which are responsible for the high MR developed in this material.
