Relation between the low-field equation of the critical de Almeida-Thouless line and critical exponents of the spin glass transition

Abstract

When one determines the critical de Almeida-Thouless line on a spin glass system by studying the equilibrium magnetisation as a function of magnetic field and temperature, the result depends on critical exponents of the spin glass transition. This offers a self-consistent check relating the low-field critical line to the critical scaling exponents on spin glass systems.
