Crossover From Individual to Collective Magnetism in Dense Nanoparticle Systems: Local Anisotropy Versus Dipolar Interactions
Elena H. Sánchez, Marianna Vasilakaki, Su Seong Lee +11
Dense systems of magnetic nanoparticles may exhibit dipolar collective behavior. However, two fundamental questions remain unsolved: i) whether the transition temperature may be af…
On the detection of surface spin freezing in iron oxide nanoparticles and its long-term evolution under ambient oxidation
M. Ghoshani, E. H. Sánchez, S. S. Lee +7
Exchange bias effects linked to surface spin freezing (SSF) are commonly found in iron oxide nanoparticles, while signatures of SSF in low-field temperature-dependent magnetization…
Energy dissipation in single-domain ferromagnetic nanoparticles: Dynamical approach
T. V. Lyutyy, S. I. Denisov, A. Yu. Peletskyi +1
We study, both analytically and numerically, the phenomenon of energy dissipation in single-domain ferromagnetic nanoparticles driven by an alternating magnetic field. Our interest…
Switching Casimir forces with Phase Change Materials
G. Torricelli, P. J. van Zwol, O. Shpak +4
We demonstrate here a controllable variation in the Casimir force. Changes in the force of up to 20% at separations of ~100 nm between Au and AgInSbTe (AIST) surfaces were achieved…
