Field-Induced Hysteresis and Quantum Tunneling of the Magnetization in a Mononuclear Manganese(III) Complex

There is plenty of room at the bottom: A gap in the literature of molecular nanomagnets has been filled with the preparation of the first mononuclear manganese(III) complex exhibiting a slow relaxation of the magnetization, that is, a species with a single slow‐relaxing, highly anisotropic MnIII ion...

Description
Summary:There is plenty of room at the bottom: A gap in the literature of molecular nanomagnets has been filled with the preparation of the first mononuclear manganese(III) complex exhibiting a slow relaxation of the magnetization, that is, a species with a single slow‐relaxing, highly anisotropic MnIII ion, as confirmed by very low‐temperature micro‐SQUID magnetization and high‐field EPR spectroscopic measurements (N blue, O red, Mn purple, Cl green).
