Extended Landau--Lifshitz equation for nanomagnets: a path-integral derivation of surface-induced magnetization nutation
H. Kachkachi, P. Thibaudeau
The authors derive an extended Landau–Lifshitz equation for nanomagnets with surface anisotropy using a spin coherent‑state path‑integral approach, showing that surface‑induced spi…
Specific absorption rate of uniaxial single-domain nanomagnets: stochastic spin dynamics versus linear response theory
H. Kachkachi
We compute the specific absorption rate of a uniaxial single-domain nanomagnet driven by an alternating magnetic field by two methods: i) direct numerical integration of the stocha…
Local-to-global heating crossover in chains of nanomagnets: A two-scale analytical framework
H. Kachkachi
We develop a two-scale analytical formalism to study heat generation and thermal transport in one-dimensional systems of nanomagnets subjected to a uniform alternating magnetic fie…
Effect of spin disorder on the specific loss power of a nanomagnet
A. Michels, H. Kachkachi
Spin non-collinearities in magnetic nanostructures arise from a variety of sources, including structural defects, finite-size effects, boundary or surface effects, Dzyaloshinskii-M…
Magnetization nutation in magnetic semiconductors: Effective spin model with anisotropic RKKY exchange interaction
H. Kachkachi
We demonstrate that the magnetization in magnetic semiconductors exhibits nutational motion when subjected to an external magnetic field. This behavior originates from the splittin…
