New specific heat data taken at very low temperatures (0.03 less than T less than 0.18K) in quasi one-dimensional helimagnet Gd(hfac)3NITiPr show a clear lambda anomaly at TN=0.039 K signaling the onset of the 3D helimagnetic phase. They match fairly well with previously reported data which showed the onset of the chiral phase transition at T0=2.08 K. Also new magnetic susceptibility data taken in the neighborhood at T0 are repeated.

Abstract
New specific heat data taken at very low temperatures (0.03 less than T less than 0.18K) in quasi one-dimensional helimagnet Gd(hfac)3NITiPr show a clear lambda anomaly at TN=0.039 K signaling the onset of the 3D helimagnetic phase. They match fairly well with previously reported data which showed the onset of the chiral phase transition at T0=2.08 K. Also new magnetic susceptibility data taken in the neighborhood at T0 are repeated.File in questo prodotto:
