Magnetization relaxation of interacting chains of nanomagnets
Denis Ledue, Renaud Patte, Francois Vernay +1
We investigate the magnetization dynamics crossover from single-particle to collective behavior in a one-dimensional chain of dipolar-coupled nanomagnets with uniaxial anisotropy.…
Low-frequency signature of magnetization nutation in nanomagnets
M. P. Adams, R. Bastardis, A. Michels +1
In this work, we show that surface anisotropy in nanomagnets induces a nutational motion of their magnetization at various frequencies, the lowest of which can be described by the…
Magnetic neutron scattering from spherical nanoparticles with Neel surface anisotropy: Atomistic simulations
Michael P. Adams, Andreas Michels, Hamid Kachkachi
We consider a dilute ensemble of randomly-oriented noninteracting spherical nanomagnets and investigate its magnetization structure and ensuing neutron-scattering response by numer…
Magnetic neutron scattering from spherical nanoparticles with Neel surface anisotropy: Analytical treatment
Michael P. Adams, Andreas Michels, Hamid Kachkachi
The magnetization profile and the related magnetic small-angle neutron scattering cross section of a single spherical nanoparticle with Neel surface anisotropy is analytically inve…
Surface-induced reduction of the switching field in nanomagnets
R. Bastardis, H. Kachkachi
Magnetization reversal in a many-spin nanomagnet subjected to an rf magnetic field, on top of a DC magnetic field, is studied by numerically solving the system of coupled (damped)…
Time profile of temperature rise in assemblies of nanomagnets
J. -L. Déjardin, H. Kachkachi
We compute the heat generated by (non-interacting) nanomagnets subjected to an alternating magnetic field (AMF) and study its transfer to the hosting medium and environment. For th…
