Abstract
Calculated Fermi surfaces of Cu1-xNix binary alloys are used to interpret m easurements of the periods of oscillations in the magnetic coupling across Cu1-xNix alloy spacers. The lack of observation of damping of such oscillat ions is shown to be the consequence of the mean free paths on the Fermi sur face being long compared with the oscillation periods. It is argued that os cillatory magnetic coupling is an important new technique for probing the F ermi surfaces of random binary alloys.
