Concentration dependence of the transition temperature in metallic spin glasses

Disordered Systems and Neural Networks 2009-11-10 v1

Abstract

The dependence of the transition temperature TgT_g in terms of the concentration of magnetic impurities cc in spin glasses is explained on the basis of a screened RKKY interaction. The two observed power laws, Tg cT_g ~ c at low cc and Tg c2/3T_g ~ c^{2/3} for intermediate cc, are described in a unified approach.
