Direct imaging of a zero-field target skyrmion and its polarity switch in a chiral magnetic nanodisk
Fengshan Zheng, Hang Li, Shasha Wang +9
A target skyrmion is a flux-closed spin texture that has two-fold degeneracy and is promising as a binary state in next generation universal memories. Although its formation in nan…
Experimental observation of magnetic bobbers for a new concept of magnetic solid-state memory
Fengshan Zheng, Filipp N. Rybakov, Aleksandr B. Borisov +11
The use of chiral skyrmions, which are nanoscale vortex-like spin textures, as movable data bit carriers forms the basis of a recently proposed concept for magnetic solid-state mem…
Low temperature pressureless immediate sintering of novel nanostructured WC/Co/NiCrSiB-alloy cemented carbide
H. Amel-Farzad, E. Taheri-Nassaj, D. Meertens +2
A novel nanostructured cemented carbide formed from WC-5%Co-20%BNi2 brazing alloy is described. During sintering, the BNi2 alloy is infiltrated into a green compact of WC-5%Co at 1…
Towards a holographic approach to spherical aberration correction in scanning transmission electron microscopy
Vincenzo Grillo, Amir H. Tavabi, Emrah Yucelen +11
Recent progress in phase modulation using nanofabricated electron holograms has demonstrated how the phase of an electron beam can be controlled. In this paper, we apply this conce…
Spherical aberration correction in a scanning transmission electron microscope using a sculpted foil
Roy Shiloh, Roei Remez, Peng-Han Lu +5
Nearly twenty years ago, following a sixty year struggle, scientists succeeded in correcting the bane of electron lenses, spherical aberration, using electromagnetic aberration cor…
Phase retrieval of an electron vortex beam using diffraction holography
Federico Venturi, Marco Campanini, Gian Carlo Gazzadi +6
In both light optics and electron optics, the amplitude of a wave scattered by an object is an observable that is usually recorded in the form of an intensity distribution in a rea…
