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…
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…
