Dynamics and thermalization of the nuclear spin bath in the single-molecule magnet Mn12-ac: test for the theory of spin tunneling
Andrea Morello, L. J. de Jongh
The description of the tunneling of a macroscopic variable in the presence of a bath of localized spins is a subject of great fundamental and practical interest, and is relevant fo…
Magnetic dipolar ordering and relaxation in the high-spin molecular cluster compound Mn6
A. Morello, F. L. Mettes, O. N. Bakharev +5
Few examples of magnetic systems displaying a transition to pure dipolar magnetic order are known to date, and single-molecule magnets can provide an interesting example. The molec…
Nuclear spin dynamics in the quantum regime of a single-molecule magnet
Andrea Morello, Oleg N. Bakharev, Hans B. Brom +2
We show that the nuclear spin dynamics in the single-molecule magnet Mn12-ac below 1 K is governed by quantum tunneling fluctuations of the cluster spins, combined with intercluste…
Long-range ferromagnetic dipolar ordering of high-spin molecular clusters
A. Morello, F. L. Mettes, F. Luis +5
We report the first example of a transition to long-range magnetic order in a purely dipolarly interacting molecular magnet. For the magnetic cluster compound Mn6O4Br4(Et2dbm)6, th…
Quantum tunnelling of magnetization in Mn12-ac studied by 55Mn NMR
A. Morello, O. N. Bakharev, H. B. Brom +1
We present an ultra-low temperature study (down to T = 20 mK) of the nuclear spin-lattice relaxation (SLR) in the 55Mn nuclei of the molecular magnet Mn12-ac. The nuclear spins act…
