What is recorded here?
Yu and colleagues used Lorentz transmission electron microscopy to image magnetic textures in a thin Fe₀.₅Co₀.₅Si film. Under a perpendicular magnetic field, they observed a hexagonal arrangement of swirling in-plane magnetization with roughly 90-nanometre spacing, and tracked its change with field and temperature. A two-dimensional spin-model Monte Carlo calculation supplied a comparison for the observed phase diagram.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The technique and transport-of-intensity analysis reconstruct in-plane magnetization; the out-of-plane spin direction was inferred by comparison with the model and field, not directly resolved by the images. The experiment concerns an electron-transparent thin specimen and finite field-temperature conditions; the experimental phase region exceeds that of the simplified simulation. It is distinct from earlier reciprocal-space neutron scattering and does not itself establish a skyrmion-based device, a universal zero-temperature phase or direct measurement of the complete three-dimensional spin field. The TIE reconstruction uses three focus planes and small-angle and weak-phase approximations; the reported Monte Carlo comparisons use finite periodic two-dimensional grids. Independent raw-image and simulation replay remain open.
