Field-direction sensitivity of Kondo hybridization in UTe

Thomas Halloran, Gicela Saucedo Salas, Sylvia K. Lewin +6

Neutron scattering experiments on the spin-triplet superconductor UTe have established that the dominant low-energy magnetic response is along Brillouin zone boundaries, resemb…

Continuum of magnetic excitations in the Kitaev honeycomb iridate DLiIrO

Thomas Halloran, Yishu Wang, K. W. Plumb +12

Inelastic neutron scattering (INS) measurements of powder DLi)(Ir)O reveal low energy magnetic excitations with a scattering cross section that is broad in…

Fragile superconductivity in a Dirac metal

Chris J. Lygouras, Junyi Zhang, Jonah Gautreau +19

Studying superconductivity in Dirac semimetals is an important step in understanding quantum matter with topologically non-trivial order parameters. We report on the properties of…

Formation of a simple cubic antiferromagnet through charge ordering in a double Dirac material

T. Berry, V. C. Morano, T. Halloran +13

The appearance of spontaneous charge order in chemical systems is often associated with the emergence of novel, and useful, properties. Here we show through single crystal diffract…

Spin-orbital order and excitons in magnetoresistive HoBi

J. Gaudet, H. -Y. Yang, E. M. Smith +11

The magnetism of the rock-salt rare-earth monopnictide HoBi, a candidate topological material with extreme magnetoresistance, is investigated. From the Ho non-Kramers…

Chemical tuning of a honeycomb magnet through a critical point

Austin M. Ferrenti, Maxime A. Siegler, Shreenanda Ghosh +9

BaCo2(AsO4)2 (BCAO) has seen extensive study since its initial identification as a proximate Kitaev quantum spin liquid candidate. Thought to be described by the highly anisotropic…

A magnetic continuum observed by terahertz spectroscopy in a quantum spin liquid candidate BaCo(AsO)

Xinshu Zhang, Yuanyuan Xu, T. Halloran +5

Quantum spin liquids (QSLs) are topologically ordered exotic states of matter that host fractionalized excitations. Kitaev proposed a particular route towards a QSL via strongly bo…

Quasi-one-dimensional exchange interactions and short-range magnetic correlations in CuTeO4

Zubia Hasan, Eli Zoghlin, Michal J. Winiarski +4

CuTeO4 has been proposed as a crystallographically distinct, yet electronic structure analog, of the superconducting cuprates. Here, we present detailed characterization of the of…

Monopolar and dipolar relaxation in spin ice HoTiO

Yishu Wang, T. Reeder, Y. Karaki +9

When degenerate states are separated by large energy barriers, the approach to thermal equilibrium can be slow enough that physical properties are defined by the thermalization pro…

Low Energy Magneto-optics of TbTiO in [111] Magnetic Field

Xinshu Zhang, Yi Luo, T. Halloran +4

The pyrochlore magnet TbTiO shows a lack of magnetic order to low temperatures and is considered to be a quantum spin liquid candidate. We perform time-domain THz…

A Geometrically Frustrated Trimer-Based Mott Insulator

Loi T. Nguyen, T. Halloran, Weiwei Xie +3

The crystal structure of Ba4NbRu3O12 is based on triangular planes of elongated Ru3O12 trimers oriented perpendicular to the plane. We report that it is semiconducting, that its We…
