Electrostatic Superlattices beyond 1:1 Stoichiometry
Binay P. Nayak, Prapti Kakkar, Wesley P. Korba +5
Exotic nanoparticle superstructures can be accessed by harnessing nanoparticle softness and charge regulation, features often viewed as obstacles to structural control. Here, we sh…
Valence-free open nanoparticle superlattices
Binay P. Nayak, Zinnia Mallick, Wenjie Wang +7
A cornerstone of advanced materials design is establishing a framework for assembling nanoparticle superstructures with tailored symmetries. A longstanding challenge has been assem…
Role of Magnetic Defects and Defect-engineering of Magnetic Topological Insulators
Farhan Islam, Yongbin Lee, Daniel M. Pajerowski +5
Magnetic defects play an important, but poorly understood, role in magnetic topological insulators (TIs). For example, topological surface transport and bulk magnetic properties ar…
Li-ion diffusion in single crystal LiFePO measured by muon spin spectroscopy
Ola Kenji Forslund, Rasmus Toft-Petersen, David Vaknin +6
Muon spin spectroscopy (SR) is now an established method to measure atomic scale diffusion coefficients of ions in oxides. This is achieved via the ion hopping rate, which cau…
Zero-field magnetic ground state of EuMgBi
Santanu Pakhira, Thomas Heitmann, S. X. M. Riberolles +4
Layered trigonal EuMgBi is reported to be a topological semimetal that hosts multiple Dirac points that may be gapped or split by the onset of magnetic order. Here, we repo…
Controlling Magnetic Order, Magnetic Anisotropy, and Band Topology in Semimetals and
Farhan Islam, Renu Choudhary, Yong Liu +5
Neutron diffraction and magnetic susceptibility studies show that orthorhombic single-crystals of topological semimetals and ${\rm Sr(Mn_{0.9}Zn_{0…
