Cross-over in scaling laws: A simple example from micromagnetics [PDF]
, 2002 Scaling laws for characteristic length scales (in time or in the model parameters) are both experimentally robust and accessible for rigorous analysis. In multiscale situations cross--overs between different scaling laws are observed.

Resonance in Magnetostatically Coupled Transverse Domain Walls
, 2014 We have observed the eigenmodes of coupled transverse domain walls in a pair of ferromagnetic nanowires. Although the pair is coupled magnetostatically, its spectrum is determined by a combination of pinning by edge roughness and dipolar coupling of the ...

Thermal vortex dynamics in thin circular ferromagnetic nanodisks [PDF]
, 2012 The dynamics of gyrotropic vortex motion in a thin circular nanodisk of soft ferromagnetic material is considered. The demagnetization field is calculated using two-dimensional Green's functions for the thin film problem and fast Fourier transforms.

Advanced Science, EarlyView.The human brain's imagination, which enables autonomous driving hazard avoidance by completing missing visual information, relies on Gaussian‐stochastic neuron. We report the altermagnetic RuO2 spintronic neurons integrating field‐free switching and intrinsic Gaussian stochasticity, building an all‐spin ANN for high‐quality image repairing and high ...

Advanced Science, EarlyView.A fully compensated synthetic antiferromagnet (SAF) multilayer exhibits a uniform state at zero field, without skyrmions. We use a SAF bias system to provide RKKY‐mediated exchange bias to the SAF multilayer, promoting zero‐field skyrmion stabilization and polarity control.

Modeling of long-time thermal magnetization decay in interacting granular magnetic materials [PDF]
, 2005 We present a general method to evaluate the long-time magnetization decay in granular magnetic systems. The method is based on Arrhenius-Neel kinetics with the evaluation of the energy barriers in a multidimensional space.

Time Average in Micromagnetism
Journal of Differential Equations, 1998 The authors consider a ferromagnetic material whose properties are defined by Maxwell's equations and a nonlinear Landau-Lifschitz equation and show that weak solutions exist. This is done by solving a relaxed system by the Galerkin process and allowing the parameter to tend to zero.

Advanced Electronic Materials, EarlyView.Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.
