The nonanalytic contri bution to the free energy of' interacting two-ditaaensional ferrnion systeraasis studied numerically. It is fotnnd that tlue ntruaaerical result for the singtrlar contribtrtion is wellfitted by a forum of B-j-T' T'-f (bj-jH)"7 BjjH' (#V?'Z")'-F- #'where T is tl'xe tenuper;tttrre,H the naagnetic. field and b7, bj-j, B-j- and Bp are constants. Consequences of' tlais singularityare discussed. The effects of irnpurity scattering are also briefly discu,ssed.
