The Fermi surface of random-metallic alloys and the oscillatory magnetic coupling across alloy spacers

摘要

Calculated Fermi surfaces of Cu1-xNix binary alloys are used to interpret measurements of the periods of oscillations in the magnetic coupling across Cu1-xNix alloy spacers. The lack of observation of damping of such oscillations is shown to be the consequence of the mean free paths on the Fermi surface being long compared with the oscillation periods. It is argued that oscillatory magnetic coupling is an important new technique for probing the Fermi surfaces of random binary alloys. [References: 33]
