2D van der Waals magnets: from fundamental physics to applications
Je-Geun Park, Kaixuan Zhang, Hyeonsik Cheong +5
Magnetism has played a central role in the long and rich history of modern condensed matter physics, with many foundational insights originating from theoretical studies of two-dim…
Distinct Optical Excitation Mechanisms of a Coherent Magnon in a van der Waals Antiferromagnet
Clifford J. Allington, Carina A. Belvin, Urban F. P. Seifert +9
The control of antiferromagnets with ultrashort optical pulses has emerged as a prominent field of research. Tailored laser excitation can launch coherent spin waves at terahertz f…
Exciton-driven antiferromagnetic metal in a correlated van der Waals insulator
Carina A. Belvin, Edoardo Baldini, Ilkem Ozge Ozel +11
Collective excitations of bound electron-hole pairs -- known as excitons -- are ubiquitous in condensed matter, emerging in systems as diverse as band semiconductors, molecular cry…
Trimeron-phonon coupling in magnetite
P. Piekarz, D. Legut, E. Baldini +11
Using density functional theory, we study the lattice dynamical properties of magnetite (FeO) in the high-temperature cubic and low-temperature monoclinic phases. The calcu…
Discovery of the soft electronic modes of the trimeron order in magnetite
Edoardo Baldini, Carina A. Belvin, Martin Rodriguez-Vega +9
The Verwey transition in magnetite (FeO) is the first metal-insulator transition ever observed and involves a concomitant structural rearrangement and charge-orbital orderi…
Magnetic field-dependent low-energy magnon dynamics in -RuCl3
Ilkem Ozge Ozel, Carina A. Belvin, Edoardo Baldini +4
Revealing the spin excitations of complex quantum magnets is key to developing a minimal model that explains the underlying magnetic correlations in the ground state. We investigat…
Little bits of diamond: Optically detected magnetic resonance of nitrogen-vacancy centers
Haimei Zhang, Carina Belvin, Wanyi Li +4
We give instructions for the construction and operation of a simple apparatus for performing optically detected magnetic resonance measurements on diamond samples containing high c…
Rapid and Precise Determination of Zero-Field Splittings by Terahertz Time-Domain Electron Paramagnetic Resonance Spectroscopy
Jian Lu, I. Ozge Ozel, Carina Belvin +7
Zero-field splitting (ZFS) parameters are fundamentally tied to the geometries of metal ion complexes. Despite their critical importance for understanding the magnetism and spectro…
Structural investigation of the bilayer iridate Sr3Ir2O7
Tom Hogan, Lars Bjaalie, Liuyan Zhao +5
A complete structural solution of the bilayer iridate compound Sr3Ir2O7 presently remains outstanding. Previously reported structures for this compound vary and all fail to explain…
The chiral anomaly and thermopower of Weyl fermions in the half-Heusler GdPtBi
Max Hirschberger, Satya Kushwaha, Zhijun Wang +5
The Dirac and Weyl semimetals are unusual materials in which the nodes of the bulk states are protected against gap formation by crystalline symmetry. The chiral anomaly~\cite{Adle…
Z topology and superconductivity from symmetry lowering of a 3D Dirac Metal AuPb
Leslie M. Schoop, Lilia S. Xie, Ru Chen +12
3D Dirac semi-metals (DSMs) are materials that have massless Dirac electrons and exhibit exotic physical properties It has been suggested that structurally distorting a DSM can cre…
Enhancement of Perpendicular Magnetic Anisotropy and Transmission of Spin-Hall-Effect-Induced Spin Currents by a Hf Spacer Layer in W/Hf/CoFeB/MgO Layer
Chi-Feng Pai, Minh-Hai Nguyen, Carina Belvin +3
We report that strong perpendicular magnetic anisotropy of the ferromagnetic layer in a W/CoFeB/MgO multilayer structure can be established by inserting a Hf layer as thin as 0.25…
