abstract:
New specific heat data taken at very low temperatures (0.03 < T < 0.18 K) in quasi one-dimensional helimagnet Gd (hfac)3 NITiPr show a clear λ 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. © 2006 Elsevier B.V. All rights reserved.
