Quantum Tunneling of Magnetization in Lanthanide Single‐Molecule Magnets: Bis(phthalocyaninato)terbium and Bis(phthalocyaninato)dysprosium Anions

Staircase-like structures in the hysteresis loops at 0.04 K (see picture) are shown by doped single crystals of TBA[(Pc)2]− (Pc=phthalocyaninato, TBA=tetrabutylammonium), the first lanthanide single-molecule magnet. They are assigned to resonant quantum tunneling of magnetization between entangled s... View More
