Modulating magnetic anisotropy in Ln(iii) single-ion magnets using an external electric field.

ABSTRACT: Single-molecule magnets have potential uses in several nanotechnology applications, including high-density information storage devices, the realisation of which lies in enhancing the barrier height for magnetisation reversal (U _eff). However, Ln(iii) single-ion magnets (SIMs) that have been reported recently reveal that the maximum value of U _eff values that can be obtained by modulating the ligand fields has already been achieved. Here, we have explored, using a combination of DFT and ab initio CASSCF calculations, a unique way to enhance the magnetisation reversal barrier using an oriented external electric field in three well-known Ln(iii) single-ion magnets: [Dy(Py)₅(O ^t Bu)₂]⁺ (1), [Er
