Topology and spin dynamics in magnetic molecules
S. Carretta, P. Santini, G. Amoretti +6
We investigate the role of topology and distortions in the quantum dynamics of magnetic molecules, using a cyclic spin system as reference. We consider three variants of antiferrom…
Spin dynamics of heterometallic Cr7M wheels (M = Mn, Zn, Ni) probed by inelastic neutron scattering
R. Caciuffo, T. Guidi, G. Amoretti +7
Inelastic neutron scattering has been applied to the study of the spin dynamics of Cr-based antiferromagnetic octanuclear rings where a finite total spin of the ground state is obt…
A perturbative approach to J mixing in f-electron systems: Application to actinide dioxides
N. Magnani, P. Santini, G. Amoretti +1
We present a perturbative model for crystal-field calculations, which keeps into account the possible mixing of states labelled by different quantum number J. Analytical J-mixing r…
Quantum-gate implementation in permanently coupled AF spin rings without need of local fields
F. Troiani, M. Affronte, S. Carretta +2
We propose a scheme for the implementation of quantum gates which is based on the qubit encoding in antiferromagnetic molecular rings. We show that a proper engineering of the inte…
Enhancement of rare-earth--transition-metal exchange interaction in PrFe probed by inelastic neutron scattering
N. Magnani, S. Carretta, G. Amoretti +4
The fundamental magnetic interactions of PrFe are studied by inelastic neutron scattering and anisotropy field measurements. Data analysis confirms the presence of thr…
NMR as a probe of the relaxation of the magnetization in magnetic molecules
P. Santini, S. Carretta, E. Liviotti +5
We investigate the time autocorrelation of the molecular magnetization for three classes of magnetic molecules (antiferromagnetic rings, grids and nanomagnets), in contact w…
