INVESTIGATION OF MAGNETIC MOLECULES

CONTAINING 3D AND 4F METALS

ationally designed magnetic molecules, such as single-molecule magnets

(SMMs), are regarded as potential candidates for various applications

in future molecular electronics. SMMs are above all transition metal and/or

lanthanide complexes that, beside other interesting quantum phenomena,

exhibit slow relaxation of the magnetization at the level of one molecule. We

have studied a series of metal complexes containing Co(II), Ni(II) and Dy(III)

ions showing multiple field-supported slow magnetic relaxation processes

detectedbyACsusceptibilitymeasurements.Aset ofACmagneticparameters

(isothermal susceptibilities, distribution parameters, relaxation times) have

been fitted to the experimental data by employing the multiple (two, three)-

set Debye model. Static (DC) magnetic properties of these compounds were

also studied experimentally and theoretically. By employing the standard

spin Hamiltonian, we have extracted the DC magnetic parameters (g-factor

components, zero-field splitting parameters). By combining the structural

and magnetic experimental data and quantum chemistry calculations (DFT,

ab initio) we have defined the magnetostructural correlations which provide

simple rules for tuning the SMM properties in this family of compounds.
