Polarized Neutron Measurements of the Internal Magnetization of a Ferrimagnet Across its Compensation Temperature
C. D. Hughes, K. N. Lopez, T. Mulkey +15
We present the first polarized neutron transmission image of a model Neel ferrimagnetic material, polycrystalline terbium iron garnet (Tb3Fe5O12, TbIG for short), as it is taken th…

Emergent topological quasiparticle kinetics in constricted nanomagnets
J. Guo, D. Hill, V. Lauter +4
The ubiquitous domain wall kinetics under magnetic field or current application describes the dynamic properties in nanostructured magnets. However, when the geometrical size of a…

Persistent dynamic magnetic state in artificial honeycomb spin ice
Jiasen Guo, Pousali Ghosh, Daniel Hill +5
Topological magnetic charges, arising due to the non-vanishing magnetic flux on spin ice vertices, serve as the origin of magnetic monopoles that traverse the underlying lattice ef…
