摘要
(Graph Presented) Staircase-like structures in the hysteresis loops at 0.04 K (see picture) are shown by doped single crystals of TBA[(Pc) 2Tb0.02111Y0.98111] - (Pc = phthalocyaninato, TBA = tetrabutylammonium), the first lanthanide single-molecule magnet. They are assigned to resonant quantum tunneling of magnetization between entangled states of the electron and nuclear spin systems. The Dy complex was also studied. © 2005 Wiley-VCH Verlag GmbH & Co.
