WebJul 15, 2024 · Therefore, FCC structures have 12 possible combinations of {111} and <110>. BCC closed packed plane atomic packing for a BCC {110} type plane. There are 6 planes of this type, and each contains two close <111> packed directions. BCC directions How is hexagonal close packing different from cubic close packing? WebWe investigate mono- and bi-layer islands, smaller than 3000 atoms in size and grown on fcc(111) single-crystal surfaces, that induce an uniaxial out-of-plane magnetic easy axis anisotropy, minimizing mutual dipolar interactions. The atoms in each island are ferromagnetically ordered; therefore, the islands are single domain.
