Abstract
Measurements of the field dependence of the ac susceptibility of the spin glass Eu0.4Sr0.6S have been extrapolated to zero frequency. Scaling of the nonlinear susceptibility in this limit gives exponents β = 0.5 and γ = 2.7. The temperature dependence of an exponent ν (T, H) which describes the dynamics of the system is used to define a critical line in the H-T plane.
