Ptychographic nanoscale imaging of the magnetoelectric coupling in freestanding BiFeO
Tim A. Butcher, Nicholas W. Phillips, Chun-Chien Chiu +14
Understanding the magnetic and ferroelectric ordering of magnetoelectric multiferroic materials at the nanoscale necessitates a versatile imaging method with high spatial resolutio…
Spatially reconfigurable topological textures in freestanding antiferromagnetic nanomembranes
Hariom Jani, Jack Harrison, Sonu Hooda +11
Antiferromagnets hosting real-space topological spin textures are promising platforms to model fundamental ultrafast phenomena and explore spintronics. However, to date, they have…
Magnetic Forces in Paramagnetic Fluids
T. A. Butcher, J. M. D. Coey
An overview of the effect of a magnetic field gradient on fluids with linear magnetic susceptibilities is given. It is shown that two commonly encountered expressions, the magnetic…
Intrinsic energy flow in laser-excited 3 ferromagnets
Daniela Zahn, Florian Jakobs, Hélène Seiler +6
Ultrafast magnetization dynamics are governed by energy flow between electronic, magnetic, and lattice degrees of freedom. A quantitative understanding of these dynamics must be ba…
Neutron Imaging of Paramagnetic Ions: Electrosorption by Carbon Aerogels and Macroscopic Magnetic Forces
T. A. Butcher, L. Prendeville, A. Rafferty +3
The electrosorption of Gd ions from aqueous 70 mM Gd(NO) solution in monolithic carbon aerogel electrodes was recorded by dynamic neutron imaging. The aerogels have…
Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet
Daniela Zahn, Florian Jakobs, Yoav William Windsor +8
The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a microscopi…
Neutron imaging of liquid-liquid systems containing paramagnetic salt solutions
Tim A. Butcher, G. J. M. Formon, P. Dunne +4
The method of neutron imaging was adopted to map the concentration evolution of aqueous paramagnetic Gd(NO3)3 solutions. Magnetic manipulation of the paramagnetic liquid within a m…
