• The density matrix renornaalization grotrp (DNIRG) method is applied to the anisotropicHeisenberg chain at finite teznperattrres. The free energy of Clue systena is obtained ttsing theqtzanttmm trauasfer tnatrix wluich is iteratively enl?trged in the iunaginary tinue direction. The magnetic strsceptibility auud the specific heat are calculated down to T : 0.OlJ and cornpared withtlae Bethe ansatz restrlts. The agreeraaeuat including the logarithmic correction in the magneticstrsceptibility at the isotropic point is fairly good.
