Title: Calculating the 1/f{sup {alpha}} noise exponent in metals

Abstract

Mechanisms responsible for an increase in the 1/f{sup {alpha}} noise exponent up to {alpha} = 3/2 are considered. The exponent has been calculated using the renormalization-group technique and {epsilon}-expansion in the space of d = 6-{epsilon} dimension. It is shown that the 1/f{sup {alpha}} noise exponent in pure metals varies within 1 {<=} {alpha} < 3/2 and exhibits a small maximum in the temperature dependence. Possible conditions for the disappearance of this maximum are discussed.
