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…
Wide energy-window view on the density of states and hole mobility of poly(p-phenylene vinylene)
I. N. Hulea, H. B. Brom, A. J. Houtepen +3
Using an electrochemically gated transistor, we achieved controlled and reversible doping of poly(p-phenylene vinylene) in a large concentration range. Our data open a wide energy-…
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…
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…
Metal-insulator transition in PF6 doped polypyrrole: interchain charge transfer versus electronic correlation
H. C. F. Martens, H. B. Brom, R. Menon
We performed dielectric spectroscopy on polypyrrole near the metal-insulator transition (MIT) down to 2 K. We evaluate the dependence of the plasma frequency and the scattering tim…
