Origin of magnetism in γ-fesi\u3csub\u3e 2 \u3c/sub\u3e/si(111) nanostructures
, 2021 Magnetism has recently been observed in nominally nonmagnetic iron disilicide in the form of epitaxial γ-FeSi2 nanostructures on Si(111) substrate. To explore the origin of the magnetism in γ-FeSi2/Si(111) nanostructures, we performed a systematic first ...

Zeitschrift für Physikalische Chemie, 2000 We report on the fabrication of periodic nanostructures on selected materials by short-pulse uv-laser ablation. Temporal studies reveal details of the ablation process with sub-picosecond time resolution. Biochemical applications of the nanostructures for planar waveguide technology are presented.

Ultrafast high-harmonic nanoscopy of magnetization dynamics
Nature Communications, 2021 Light induced magnetization dynamics can be as fast as few tens of femtoseconds. Here, Zayko et al show ultrafast microscopy based on high-harmonic radiation for direct imaging of ultrafast phenomena and capture femtosecond spin dynamics at the nanoscale.

Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review
Metals, 2021 Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic fields. Since the deformation

Is there a shift to “active nanostructures”? [PDF]
Journal of Nanoparticle Research, 2009 It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment.
