The Ising, the XY, and the Heisenberg models with $\pm J$ bond distributions undergo finite-temperature phase transitions with a ratio of critical exponents $γ/ν=2.4$. Evaluated critical exponents agree with corresponding experimental results. The analyses are based upon the nonequilibrium relaxation from the paramagnetic state and the finite-time scaling.5 pages, 2 figures, an article for the Proceedings of the 2003 CSP workshop at The University of GeorgiaDisordered Systems and Neural Networkstext
