Antiferromagnetic Nanoscale Bit Arrays of Magnetoelectric Cr2O3 Thin Films

Magnetism of oxide antiferromagnets (AFMs) has been studied in single crystals and extended thin films. The properties of AFM nanostructures still remain underexplored. Here, we report on the fabrication and magnetic imaging of granular 100 nm-thick magnetoelectric Cr2O3 films patterned in circular bits with diameters ranging from 500 down to…

Domain Wall Automotion by Cross Section Tailoring in Ferromagnetic Nanostripes

Curvilinear magnetism of nanostripes is a prospective playground both for fundamental research and numerous applications. By tailoring geometrical properties of the ferromagnetic stripes and wires there appear new possibilities to control its magnetic properties such as the dynamics of the domain walls. Deterministic fast motion of the domain walls is…
