摘要：

Experimental results for the temperature dependence of susceptibility and specific heat of microcrystalline Gd(hfac)(3)NITEt are presented. The data are compared with transfer matrix calculations, in a one-dimensional classical planar model with competing nearest- and next-nearest-neighbour exchange interactions, leading to helical spin arrangement with chiral degeneracy. A peak at T similar or equal to 2 K in the T-dependence of the specific heat is interpreted in terms of the excitation of chiral domain walls, separating two domains of opposite chirality.
