Probing spin waves using single-spin magnetometry
, 2019 Spin waves are the elementary spin excitations of magnetic materials. This paper presents the use of nitrogen-vacancy spins in diamond to study spin-wave resonances, thermally excited spin waves, and spin-wave chemical potentials.

Chiral Phase Change Nanomaterials
Advanced Functional Materials, EarlyView.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Three-dimensional spin-wave dynamics, localization and interference in a synthetic antiferromagnet
Nature CommunicationsSpin waves are collective perturbations in the orientation of the magnetic moments in magnetically ordered materials. Their rich phenomenology is intrinsically three-dimensional; however, the three-dimensional imaging of spin waves has so far not been ...

Topological Spin Excitations in Honeycomb Ferromagnet CrI_{3}
Physical Review X, 2018 In two-dimensional honeycomb ferromagnets, bosonic magnon quasiparticles (spin waves) may either behave as massless Dirac fermions or form topologically protected edge states.

Novel itinerant transverse spin waves [PDF]
, 2009 Thesis advisor: Kevin S. BedellIn 1956, Lev Davidovich Landau put forth his theory on systems of interacting fermions, or fermi liquids. A year later, Viktor Pavlovich Silin described spin waves that such a system of fermions would support.

On quantum and relativistic mechanical analogues in mean field spin models [PDF]
, 2014 Conceptual analogies among statistical mechanics and classical or quantum mechanics often appeared in the literature. For classical two-body mean field models, such an analogy is based on the identification between the free energy of Curie-Weiss type ...

Advanced Functional Materials, EarlyView.Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...
