Fast Pixelated Detectors in Scanning Transmission Electron Microscopy. Part I: Data Acquisition, Live Processing and Storage
Magnus Nord, Robert W. H. Webster, Kirsty A. Paton +4
The use of fast pixelated detectors and direct electron detection technology is revolutionising many aspects of scanning transmission electron microscopy (STEM). The widespread ado…
Spontaneous creation and annihilation dynamics and strain-limited stability of magnetic skyrmions
Frederic Rendell-Bhatti, Raymond J. Lamb, Johannes W. van der Jagt +3
Magnetic skyrmions are topological magnetic spin structures exhibiting particle-like behaviour. They are of strong interest from a fundamental viewpoint and for application, where…
Ice-rule made manifold: phase transitions, topological defects and manifold restoration in two-dimensional artificial spin systems
Gavin M. Macauley, Gary W. Paterson, Yue Li +3
Artificial spin ices are arrays of correlated nano-scale magnetic islands that prove an excellent playground in which to study the role of topology in critical phenomena. Here, we…
Heisenberg pseudo-exchange and emergent anisotropies in field-driven pinwheel artificial spin ice
Gary W. Paterson, Gavin M. Macauley, Yue Li +8
Rotating all islands in square artificial spin ice (ASI) uniformly about their centres gives rise to the recently reported pinwheel ASI. At angles around 45, the antif…
Sub-100 nanosecond temporally resolved imaging with the Medipix3 direct electron detector
Gary W. Paterson, Raymond J. Lamb, Rafael Ballabriga +3
Detector developments are currently enabling new capabilities in the field of transmission electron microscopy (TEM). We have investigated the limits of a hybrid pixel detector, Me…
Effect of disorder on the collective excitations of the chiral spin soliton lattice
F. J. T. Goncalves, Y. Shimamoto, T. Sogo +3
We assess the impact of magnetic disorder on the spin excitation spectra of the chiral helimagnetic crystal using microwave resonance spectroscopy. The chiral…
Order and Disorder in the Magnetisation of the Chiral Crystal CrNbS
Gary W. Paterson, Tsukasa Koyama, Misako Shinozaki +9
Competing magnetic anisotropies in chiral crystals with Dzyaloshinskii Moriya exchange interactions can give rise to non-trivial chiral topological magnetisation configurations wit…
