A Six-Coordinate Ytterbium Complex Exhibiting Easy-Plane Anisotropy and Field-Induced Single-Ion Magnet Behavior

The field-induced blockage of magnetization behavior
was first
observed in an YbIII-based molecule with a trigonally distorted
octahedral coordination environment. Ab initio calculations and micro-SQUID
measurements were performed to demonstrate the exhibition of easy-plane
anisotropy, suggesting the investigated complex is the first pure
lanthanide field-induced single-ion magnet (field-induced SIM) of
this type. Furthermore, we found the relaxation time obeys a power
law instead of an exponential law, indicating that the relaxation
process should be involved a direct process rather than an Orbach
process.
