In-Field and Zero-Field Relaxation Dynamics of Dysprosocenium in Solution.

ABSTRACT: Most of the work in expanding the frontiers of single-molecule magnets employs the chemical design of new molecules to increase the size of the effective barrier (U_eff) or the hysteresis temperature (T_H). Here we explore how perturbing the local environment affects magnetic relaxation properties by dissolving [Dy(Cp^ttt)₂][B(C₆F₅)₄] in two different solvents: difluorobenzene (DFB) and dichloromethane (DCM). Surprisingly, we find no significant effects in the phonon-driven Raman-I regime at higher temperatures, but we do observe that the frozen-solution environment increases the rate of quantum tunneling of the magnetization (QTM) due to an increase in the size of the avoided level crossing. We find th
