Asymmetric Magnetic Relaxation behavior of Domains and Domain Walls Observed Through the FeRh First-Order Metamagnetic Phase Transition
Jamie R. Massey, Rowan C. Temple, Trevor P. Almeida +8
The phase coexistence present through a first-order phase transition means there will be finite regions between the two phases where the structure of the system will vary from one…
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…
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…
Ultrafast holography enabled by quantum interference of ultrashort electrons
I. Madan, G. M. Vanacore, E. Pomarico +7
Holography relies on the interference between a known reference and a signal of interest to reconstruct both the amplitude and phase of that signal. Commonly performed with photons…
Antiferromagnetic-ferromagnetic phase domain development in nanopatterned FeRh islands
R. C. Temple, T. P. Almeida, J. R. Massey +9
The antiferromagnetic to ferromagnetic phase transition in B2-ordered FeRh is imaged in laterally confined nanopatterned islands using photoemission electron microscopy with x-ray…
Ultrafast Generation and Control of an Electron Vortex Beam via Chiral Plasmonic Near Fields
G. M. Vanacore, G. Berruto, I. Madan +12
Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous wave electron vortex beams are commonly…
