The displacement of atoms in a magnetic trilayer Fe (10 nm)/Cr (0.7 nm)/Fe (10 nm) system by 30 keV Ga+ ion irradiation was studied by 3D Atom Probe Tomography (APT). From APT, the positions of individual Cr and Fe atoms could be located with sub-nm

Fatigue fracture surfaces of high-strength steels generated by a very high number of cycles to failure show so-called fine granular areas, for which the crack initiation and propagation mechanism is not fully understood. To clarify this mechanism of

High-strength steels exhibit different fracture surface characteristics under cyclic load when failure is initiated by non-metallic inclusions depending on the lifespan. These can be attributed to different crack propagation mechanisms. These charact

The irradiation of glass surfaces by 30 keV Ga + ions under oblique incidence angles results in the development of “ripple”-like nanostructures. The evolution of these ripples was monitored in situ in the ion fluence range from 3 × 10 16 to 1 ×

We demonstrate that antiferromagnetically coupled Fe/Cr/Fe trilayers can be magnetically patterned on the micrometer and sub-micrometer scale by irradiation with keV Ga + ions, which induces a local transition to ferromagnetic coupling due to direct

We investigate the formation of magnetic domains in a magnetic trilayer patterned using ion beam bombardment. The system consists of a finite array of in-plane magnetized ferromagnetic Fe elements embedded into an antiferromagnetically coupled Fe∕C
