We realize a magnetic skyrmion diode operated by unidirectional transport that flows in only one direction, which is highly significant for information processing spintronic and nanoelectronic devices. easily control the engineering asymmetric shapes of geometric structures. Here, we present simple method to describe underlying mechanism behind characterizing topography potential energy surfaces from purely perspective. Our approach enables deeper physical insight into manipulation efficient...
Skyrmions, topologically stable magnetic solitons characterized by whirling magnetization in nanoscale elements, show promise information carriers spintronics and spin-based quantum computing due to their unique properties: small size, stability, controllability. In this study, we introduce a novel method of skyrmion generation through domain wall deformation dynamics. Our analytical micromagnetic simulations demonstrate that motion exceeding the Walker threshold induces topological walls...
The dynamic behaviors of magnetic domain walls have significant implications for developing advanced spintronic devices. In this study, we investigate the intriguing resonance phenomenon within wall structure and its profound influence on motion, focusing dissipation mechanism. By applying a static external field, observe remarkable amplification velocity, surpassing limitations conventional one-dimensional model. To quantify enhancement, introduce novel parameter, distortion variation rate,...
