Probing Light Atoms at Sub-nanometer Resolution: Realization of Scanning Transmission Electron Microscope Holography
Fehmi S. Yasin, Tyler R. Harvey, Jordan J. Chess +4
Atomic resolution imaging in transmission electron microscopy (TEM) and scanning TEM (STEM) of light elements in electron-transparent materials has long been a challenge. Biomolecu…
Interpretable and efficient contrast in scanning transmission electron microscopy with a diffraction grating beamsplitter
Tyler R. Harvey, Fehmi S. Yasin, Jordan J. Chess +9
Efficient imaging of biomolecules, 2D materials and electromagnetic fields depends on retrieval of the phase of transmitted electrons. We demonstrate a method to measure phase in a…
Resonant properties of dipole skyrmions in amorphous Fe/Gd multilayers
S. A. Montoya, S. Couture, J. J. Chess +9
The dynamic response of dipole skyrmions in Fe/Gd multilayer films is investigated by ferromagnetic resonance measurements and compared to micromagnetic simulations. We detail thic…
A streamlined approach to mapping the magnetic induction of skyrmionic materials
Jordan J. Chess, Sergio A. Montoya, Tyler R. Harvey +5
Recently, Lorentz transmission electron microscopy (LTEM) has helped researchers advance the emerging field of magnetic skyrmions. These magnetic quasi-particles, composed of topol…
Tailoring magnetic energies to form dipole skyrmions and skyrmion lattices
S. A. Montoya, S. Couture, J. J. Chess +11
The interesting physics and potential memory technologies resulting from topologically protected spin textures such as skyrmions, has prompted efforts to discover new material syst…
Synthesizing Skyrmion Molecules in Fe-Gd Thin Films
J. C. T Lee, J. J. Chess, S. A. Montoya +9
We show that properly engineered amorphous Fe-Gd alloy thin films with perpendicular magnetic anisotropy exhibit room-temperature skyrmion molecules, or a pair of like-polarity, op…
