Standard finite size scaling analysis of the data suggests the existence of a transition at ¿c=0.64±0.08. Results are compared with existing theories and with the study of metastable avalanches in the same model.4 p.application/pdfeng(c) The American Physical Society, 1999Física estadísticaTermodinàmicaSistemes dinàmics diferenciablesMaterials magnèticsPropietats magnètiquesMagnetic properties and materialsStatistical physicsThermodynamicsDifferentiable dynamical systemsMagnetic materialsMagnetic propertiesNumerical signs fos a transition in the 2d Random Field Ising Model at T=0info:eu-repo/semantics/article151687info:eu-repo/semantics/openAccess
