Noncollinear 2k Antiferromagnetism in the Zintl Semiconductor Eu5In2Sb6

January 29, 2024
Author(s)
Vincent Morano, Jonathan N. Gaudet, Nicodemos Varnava, Tanya Berry, Thomas Halloran, Chris Lygouras, Xiaoping Wang, Christina M. Hoffman, Guangyong Xu, Jeffrey Lynn, Tyrel McQueen, David Vanderbilt, Collin L. Broholm
Eu5In2Sb6 is an orthorhombic non-symmorphic small band gap semiconductor with three distinct Eu2+ sites and two low-temperature magnetic phase transitions. The material displays one of the greatest (negative) magnetoresistances of known stoichiometric

Stripe Helical Magnetism and Two Regimes of Anomalous Hall Effect in NdAlGe

March 27, 2023
Author(s)
Hung-Yu Yang, Jonathan N. Gaudet, Rahul Verma, Santu Baidya, Faranak Bahrami, Xiaohan Yao, Cheng-Yi Huang, Lisa Debeer-Schmitt, Adam A. Aczel, Guangyong Xu, Hsin Lin, Arun Bansil, Bahadur Singh, Fazel Tafti
We report the magnetic and electronic transport properties of the inversion and time-reversal symmetry breaking Weyl semimetal NdAlGe. This material is analogous to NdAlSi whose helicalmagnetism is a rare example of a Weyl-mediated collective phenomenon

Spin-orbital order and excitons in magnetoresistive HoBi

March 22, 2023
Author(s)
Jonathan N. Gaudet, H. Yang, E. Smith, T. Halloran, J. Clancy, Jose Rodriguez Rivera, Guangyong Xu, Yang Zhao, Wangchun Chen, G. Sala, Adam A. Aczel, B. Gaulin, Fazel Tafti, Collin L. Broholm
The magnetism of the rock-salt fcc rare-earth monopnictide HoBi, a candidate topological material with extreme magnetoresistance, is investigated. From the Ho3+ non-Kramers J=8 spin-orbital multiplet, the cubic crystal electric field yields six near

Incommensurate Magnetic Orders and Possible Topological Hall Effect in the Square-Net Centrosymmetric EuGa 2 Al 2 System

July 7, 2022
Author(s)
Jaime Moya, Shiming Lei, Eleanor Clements, Caitlin Kengle, Stella Sun, Kevin Allen, Qizhi Li, Y. Peng, Ali Husain, Matteo Mitrano, Matthew Krogstad, Raymond Osborn, Anand Puthirath, Songxue Chi, Lisa Debeer-Schmitt, Jonathan N. Gaudet, P. Abbamonte, Jeffrey Lynn, E. Morosan
Neutron diffraction on the centrosymmetric square-net magnet EuGa 2 Al 2 reveals multiple incommensurate magnetic states (AFM1,2,3) in zero field. In applied field, a new magnetic phase (A) is identified from magnetization and transport measurements

Antiferromagnetic Order and Spin-Canting Transition in the Corrugated Square Net Compound Cu 3 (TeO 4 )(SO 4 ):H 2 O

July 19, 2021
Author(s)
Zhi-Cheng Wang, Kulatheepan Thanabalasingam, Jan P. Scheifers, Alenna Streeter, Gregory T. McCandless, Jonathan N. Gaudet, Craig Brown, Carlo U. Segre, Julia Y. Chan, Fazel Tafti
Strongly correlated electrons in layered perovskite structures have been the birthplace of high-temperature superconductivity, spin liquid, and quantum criticality. Specifically, the cuprate materials with layered structures made of corner sharing square
