TL;DR: In this article, a two-dimensional square lattice of skyrmions on the atomic length scale was described as the magnetic ground state of a hexagonal Fe film of one-atomic-layer thickness on the Ir(111) surface.

TL;DR: This work reports on an ultrathin magnetic film in which individual skyrmions can be written and deleted in a controlled fashion with local spin-polarized currents from a scanning tunneling microscope, demonstrating the feasibility of using spin- polarized tunnel currents for the controlled manipulation of individual sk Kyrmions.

TL;DR: It is shown that the broken inversion symmetry at the surface promotes one direction of the vector spin chirality, leading to a unique rotational sense of the spiral in all chains, suggesting a new way of transmitting information about the state of magnetic objects on the nanoscale.

TL;DR: The orbital symmetry of the spin-polarized density of states of single cobalt atoms is taken advantage to unambiguously determine their spin direction in real space using a combination of spin-resolved scanning tunnelling microscopy experiments and ab initio calculations.

TL;DR: Spin-resolved scanning tunneling microscopy is used to reveal a commensurate hexagonal nanoskyrmion lattice in the hcp stacked Fe monolayer on Ir(111) due to magnetic interactions between the Fe atoms and the Ir substrate.
