Spin Glasses in Transition?

Abstract

Spin glasses have variously been described as apparently frozen but very slowly relaxing spin systems, and also as magnetic phases below a second order transition. The structural and dynamic properties of metallic spin glasses are surveyed with emphasis on neutron scattering and low field magnetic measurements. Spin glass regions in phases with magnetic long range order are included, and an attempt is made to assess spin glass theories with respect to the various transitions.
