By Monte Carlo simulations it is shown that the magnetization M (T, H) of the two-dimensional nearest-neighbor Edwards-Anderson model is proportional to H^1-x, essentially independent of temperature T, for fields H<{H₂}^eq (T), with {H₂}^eq (T) T^1{x}, the exponent being x0. 280. 06. Irreversible behavior on a time scale t sets in for a field H₂ (t) where H₂ (t) {T₅ (t) } nearly follows the De Almeida-Thouless line, although no static nonzero freezing temperature T₅ exists. Consequences for the interpretation of related experimental work are discussed.
Kinzel et al. (1983) studied this question.
