Abstract

From measurements of the magnetic properties of some dilute CuMn alloys we have determined the strength of the Ruderman-Kittel-Kasuya-Yosida interaction,

V (r) = \frac{(V_{0} cos 2 k_{F} r)}{r^{3}}

, to be

V_{0} = 7.5 \times 10^{- 37}

erg

{cm}^{3}

. The corresponding value of the

s

d

exchange parameter is

| J | = 2.2

eV.
