ساختارهای پیچیده برای حافظه نانو مغز ناشی از تعامل دوقطبی دیوپل در دیسک های تک لایه

We find in simulations that, magnetic vortices induced by the DDI show no chirality, the multi-vortex structures simulated with two quantum methods agree well with each other, both external magnetic field and uniaxial anisotropy perpendicular to the disk-plane can help stabilize the vortical textures if DDI is not strong enough, providing new techniques for nanomagnetic data storage and computing.Download high-res image (866KB)Download full-size image
