Micromagnetic analysis of magnetization reversal in Fe77.5Si7.5B15 amorphous glass-coated nanowires

AIP Advances, 2019
A micromagnetic model based on the finite element method (FEM) is proposed in order to investigate the specific role of the magnetoelastic anisotropy in the axial magnetization reversal process of highly magnetostrictive amorphous glass-coated nanowires ...

Intrinsic Curie temperature bistability in ferromagnetic semiconductor resonant tunneling diodes

, 2005
We predict bistability in the Curie temperature-voltage characteristic of double barrier resonant-tunneling structures with dilute ferromagnetic semiconductor quantum wells. Our conclusions are based on simulations of electrostatics and ballistic quantum

On the Ordering Mechanism of Cu+ in 2D van der Waals Multiferroic CuCrP2S6

Advanced Science, EarlyView.
Temperature‐dependent X‐ray single‐crystal diffuse scattering measurements of CuCrP2S6 in the (H, K, 0) plane reveal the gradual emergence and strengthening of short‐range order upon cooling from 230 to 170 K. At intermediate temperatures, diffuse features become pronounced and eventually lock into sharp incommensurate satellite reflections, indicating

Investigating Phase Separation in Genome Folding via Multiscale Computational Modeling

Advanced Science, EarlyView.
Phase separation is emerging as a multiscale organizing principle of genome folding across scales, from nucleosomes and transcriptional condensates to chromatin domains and nuclear compartments. By integrating physics‐based simulations with data‐driven inference, computational modeling now links molecular interactions to nuclear architecture and points

Mesoscopic models for definition of the large-scale elastic properties of the soft magnetic elastomers

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
A pair of magnetizing particles embedded in a cylinder made of a highelasticity (hyperelastic) material is considered as a model of a mesoscopic structure element of a soft magnetic elastomer. In the presence of the magnetic field particles magnetize and

A charge-driven feedback loop in the resonance fluorescence of a single quantum dot

, 2016
Semiconductor quantum dots can emit antibunched, single photons on demand with narrow linewidths. However, the observed linewidths are broader than lifetime measurements predict, due to spin and charge noise in the environment. This noise randomly shifts
