Abstract

The exact expressions for the second and third frequency moments of the transverse spin susceptibility (χ±) of a magnetic electron gas are derived. A subtracted dispersion relation incorporating the first few moments for it is derived from which the longwave spinwave dispersion is obtained. © 1973.
