Switching of Magnetic Moments of Nanoparticles by Surface Acoustic Waves
J. Tejada, E. M. Chudnovsky, R. Zarzuela +4
We report evidence of the magnetization reversal in nanoparticles by surface acoustic waves (SAWs). The experimental system consists of isolated magnetite nanoparticles dispersed o…
Onset of a Propagating Self-Sustained Spin Reversal Front in a Magnetic System
P. Subedi, S. Vélez, F. Macià +6
The energy released in a magnetic material by reversing spins as they relax toward equilibrium can lead to a dynamical instability that ignites self-sustained rapid relaxation alon…
Crystal defects and spin tunneling in single crystals of Mn12 clusters
J. M. Hernandez, F. Torres, E. Molins +1
The question addressed in this paper is that of the influence of the density of dislocations on the spin tunneling in Mn12 clusters. We have determined the variation in the mosaici…
Relaxation and Landau-Zener experiments down to 100 mK in ferritin
M. Duran, E. del Barco, J. M. Hernandez +1
Temperature-independent magnetic viscosity in ferritin has been observed from 2 K down to 100 mK, proving that quantum tunneling plays the main role in these particles at low tempe…
Giant and time-dependent magnetocaloric effect in high-spin molecular magnets
F. Torres, J. M. Hernandez, X. Bohigas +1
We have measured and calculated the magnetocaloric effect in macroscopic samples of oriented high-spin molecular clusters like Mn12 and Fe8 as a function of the temperature and bot…
High frequency resonant experiments in Fe molecular clusters
E. del Barco, J. M. Hernandez, J. Tejada +5
Precise resonant experiments on Fe magnetic clusters have been conducted down to 1.2 K at various tranverse magnetic fields, using a cylindrical resonator cavity with 40 diff…
