Observation of zero-point quantum fluctuations of a single-molecule magnet through the relaxation of its nuclear spin bath
A. Morello, A. Millán, L. J. de Jongh
A single-molecule magnet placed in a magnetic field perpendicular to its anisotropy axis can be truncated to an effective two-level system, with easily tunable energy splitting. Th…
Pressure effects in hollow and solid iron oxide nanoparticles
N. J. O. Silva, S. Saisho, M. Mito +5
We report a study on the pressure response of the anisotropy energy of hollow and solid maghemite nanoparticles. The differences between the maghemite samples are understood in ter…
Shifted loops and coercivity from field imprinted high energy barriers in ferritin and ferrihydrite nanoparticles
N. J. O. Silva, V. S. Amaral, A. Urtizberea +8
We show that the coercive field in ferritin and ferrihydrite depends on the maximum magnetic field in a hysteresis loop and that coercivity and loop shifts depend both on the maxim…
Non-linear response of single-molecule magnets: field-tuned quantum-to-classical crossovers
R. Lopez-Ruiz, F. Luis, A. Millan +3
Quantum nanomagnets can show a field dependence of the relaxation time very different from their classical counterparts, due to resonant tunneling via excited states (near the anis…
Nonlinear response of single-molecule nanomagnets: equilibrium and dynamical
R. López-Ruiz, F. Luis, V. González +2
We present an experimental study of the {\em nonlinear} susceptibility of Mn single-molecule magnets. We investigate both their thermal-equilibrium and dynamical nonlinear r…
Large quantum nonlinear dynamic susceptibility of single-molecule magnets
F. Luis, V. Gonzalez, A. Millan +1
The nonlinear dynamical response of Mn single-molecule magnets is experimentally found to be very large, quite insensitive to the spin-lattice coupling constant, and display…
