Abstract
We present results concerning the static and dynamic behaviour of the new Ising spin glass Fe0.35Mg0.65Br2. The analysis of the static magnetisation leads to conclude to a transition at finite Tc = 1.9 K with γ = 2 and β = 0.4. Dynamics confirm this feature and we find critical exponent zv ~ 10.
