This is known both numerically and from calculations that are special to each model. This value of the exponent contrasts with ν = 1 4 for the unfrustrated systems at Tc. The purpose of this paper is to develop a common method that is applicable to both frustrated and unfrustrated systems. © 1995.Mahidol UniversityMaterials SciencePhysics and AstronomyArticleSCOPUS10.1016/0304-8853(94)00948-1
