![]() ![]() One of the most important crystal structures adopted by metals is characterized by the "abcabc".stacking of close- packed layers. Use of the Primitive Unit Cell in Understanding Subtle Features of the Cubic Closest- Packed StructureĮRIC Educational Resources Information Center Moreover, an inhomogeneous current induces a sliding motion of pancake Skyrmions, indicating that they behave as effective mesoscale particles. ![]() Unbiased Monte Carlo simulations and simple stabilization arguments reveal face centered cubic and hexagonal close packed Skyrmion crystals for different choices of the interlayer exchange, in addition to the conventional triangular crystal of Skyrmion lines. The way in which Skyrmion disks or "pancake Skyrmions" pile up in layered centrosymmetric materials is dictated by the interlayer exchange. This situation is analogous to the so-called pancake vortices of quasi-two-dimensional superconductors. Skyrmions are disklike objects that typically form triangular crystals in two-dimensional systems. Face Centered Cubic and Hexagonal Close Packed Skyrmion Crystals in Centrosymmetric Magnets ![]()
