We analyze the magnetic behavior of the five uranium-based SIMs reported in the literature. By combining a corrected crystal field model with the magnetic experimental data, we obtain the lowest-lying magnetic levels and the associated wave functions of the nanomagnets, which are found to be compatible with the observed SMM behavior. Additionally, this approach has allowed us to propose some geometrical considerations and practical advice for experimentalists aiming for the rational design of SIMs and spin qubits based on uranium. 2À), 27 and two polynuclear complexes: the trimetallic cluster {Np VI O 2 Cl 2 }{Np V O 2 Cl(thf) 3 } 2 , 28 also

A neutron spectroscopy experiment has been performed to observe the position of the crystal-field levels in both the paramagnetic and antiferromagnetic phases of UOS. The J-4 ground manifold undergoes an overall splitting of about 100 meV in agreement with the predictions of a crystal-field model used to analyse specific heat data. Above TN, two main peaks are observed at 74 and 82 meV with a shoulder at about 87 meV. Below TN there is a redistribution of intensity together with a shift of the peak positions to 76, 84 and 92 meV at T=30 K. The experimental observations are interpreted in the framework of a refined crystal-field model.
