Ring-exchange interaction effects on magnons in the Dirac magnet CoTiO3

May 21, 2024
Author(s)
Yufei Li, Thuc Mai, Mohammed Karaki, Evan Jasper, Kevin Garrity, Chase Lyon, Daniel Shaw, Timmothy DeLazzer, Adam Biacchi, Rebecca Dally, Daniel Heligman, Jared Gdanski, Tehseen Adel, Maria Munoz, Alex Giovannone, Amit Pawbake, Clement Faugeras, Jeffrey Simpson, Kate Ross, Nandini Trivedi, Yuanming Lu, Angela R. Hight Walker, Rolando Valdes Aguilar
In magnetically ordered materials with localized electrons, it has been known for a long time [1–3] that the fundamental interactions are due to exchange of electrons. In most cases only the interaction between pairs of spins in neighboring atoms is taken

Noncryogenic Air Separation using Aluminum Formate Al(HCOO) 3 (ALF)

Dinesh Mullangi, Hayden Evans, Taner N. Yildirim, Yuxiang Wang, Zeyu Deng, Zhaoqiang Zhang, Thuc Mai, Fengxia Wei, John Wang, Angela R. Hight Walker, Craig Brown, Dan Zhao, Pieremanuele Canepa, Anthony K. Cheetham
Separating oxygen from air to create oxygen-enriched gas streams is a process that is significant in both industrial and medical fields. However, the prominent technologies for creating oxygen-enriched gas streams are both energy and infrastructure

Elemental excitations in MoI3 one-dimensional van der Waals nanowires

Fariborz Kargar, Zahra Barani, Nicholas Sesing, Thuc Mai, Topojit Debnath, Huairuo Zhang, Yuhang Liu, Yanbing Zhu, Subhajit Ghosh, Adam Biacchi, Felipe H. da Jornada, Ludwig Bartels, Tehseen Adel, Angela R. Hight Walker, Albert Davydov, Tina Salguero, Roger Lake, Alexander Balandin
We report the polarization-dependent Raman spectrum of exfoliated MoI3, a van der Waals material with a "true one-dimensional" crystal structure that can be exfoliated to individual atomic chains. The temperature evolution of several Raman features reveals

Distinct magneto-Raman signatures of spin-flip phase transitions in CrI3

Amber D. McCreary, Thuc T. Mai, Franz Utermohlen, Jeffrey R. Simpson, Kevin F. Garrity, Xiaozhou Feng, Dmitry Shcherbakov, Yanglin Zhu, Jin Hu, Daniel Weber, Kenji Watanabe, Takashi Taniguchi, Joshua Goldberger, Zhiqiang Mao, Chun Ning Lau, Yuanming Lu, Nandini Trivedi, Rolando Valdes Aguilar, Angela R. Hight Walker
The discovery of 2-dimensional (2D) materials, such as CrI3, that retain magnetic ordering down to monolayer thickness, and even more have layer-dependent magnetic properties has led to a plethora of research in 2D magnetism. Here, we report a magneto

Enhanced magnetization in proton irradiated Mn3Si2Te6 van der Waals crystals

L. M. Martinez, H. Iturriaga, R. Olmos, L. Shao, Y. Liu, Thuc Mai, C. Petrovic, Angela R. Hight Walker, S. R. Singamaneni
van der Waals (vdW) engineering of magnetism is a topic of increasing research interest in the community at present. We study the magnetic properties of quasi-two-dimensional layered vdW Mn3Si2Te6 (MST) crystals upon proton irradiation as a function of

Quasi-two-dimensional magnon identification in antiferromagnetic FePS3 via magneto-Raman spectroscopy

February 18, 2020
Author(s)
Amber D. McCreary, Jeffrey R. Simpson, Thuc T. Mai, Robert D. McMichael, Jason E. Douglas, Nicholas P. Butch, Cindi L. Dennis, Rolando Valdes Aguilar, Angela R. Hight Walker
Recently it was discovered that van der Waals-bonded magnets retain long range magnetic ordering even down to a monolayer thickness, opening many avenues in fundamental physics and potential applications of these fascinating materials. One example is FePS3

Polarization-resolved Raman spectroscopy of \alpha-RuCl3 and evidence of room temperature two-dimensional magnetic scattering

October 14, 2019
Author(s)
Thuc T. Mai, Amber D. McCreary, P. Lampen-Kelley, Nicholas P. Butch, Jeffrey R. Simpson, J.-Q. Yan, S. E. Nagler, D. Mandrus, Angela R. Hight Walker, Rolando Valdes Aguilar
Polarization-resolved Raman spectroscopy was performed and analyzed from large, high quality, mono-domain single crystal of \alpha-RuCl3, a proximate Kitaev quantum spin liquid. Spectra were collected with laser polarizations parallel and perpendicular to
