Enhanced Magnetism in Cation‐Modulated Manganite Heterostructures
Advanced Materials Interfaces, EarlyView.Magnetic contrast is introduced within a single manganite system via a small modulation of the cation ratio. Enhanced magnetization occurs in superlattices with small stoichiometric differences. The combined SQUID, polarized neutron reflectometry, and x‐ray absorption spectroscopy results are consistent with the interfacial electronic reconstruction ...

Direct Observation of Anapoles by Neutron Diffraction [PDF]
Physical Review Letters, 2019 The scope of magnetic neutron scattering has been expanded by the observation of electronic Dirac dipoles (anapoles) that are polar (parity-odd) and magnetic (time-odd). A zero-magnetization ferromagnet Sm0.976Gd0.024Al2 with a diamond-type structure presents Dirac multipoles at basis-forbidden reflections that include the standard (2, 2, 2) reflection.

Extrinsic Limitations of Stealthy Hyperuniform Devices
Advanced Optical Materials, EarlyView.Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...
