N2 - The electromagnetic properties of a Cu75-Fe5-Ni 20 alloy have been investigated upon isothermal annealing of the alloy at 873 K, using a superconducting quantum interference device (SQUID) magnetometer and a physical property measurement system (PPMS) instrument. Magnetoresistance (MR) was closely related to the magnetization value in specimens of the alloy. The most striking finding of the present work is that the as-quenched specimen with no visible precipitates attains the largest MR (∼16%at H = 7T and T = 10K), although fine precipitates with a proper size were thought to be essential in our previous studies. The present investigation also revealed that several significant effects accompanied the magnetic and magnetoresistive properties, with microstructural evolution occurring during the phase decomposition of a Cu75-Fe5-Ni20 alloy.
