Non-collinear 2k antiferromagnetism in the Zintl semiconductor EuInSb
Vincent C. Morano, Jonathan Gaudet, Nicodemos Varnava +10
EuInSb is an orthorhombic non-symmorphic small band gap semiconductor with three distinct Eu sites and two low-temperature magnetic phase transitions. The materi…
A new noncollinear ferromagnetic Weyl semimetal with anisotropic anomalous Hall effect
Hung-Yu Yang, Bahadur Singh, Jonathan Gaudet +18
A developing frontier in condensed matter physics is the emergence of novel electromagnetic responses, such as topological and anomalous Hall effect (AHE), in ferromagnetic Weyl se…
Incommensurate magnetism mediated by Weyl fermions in NdAlSi
Jonathan Gaudet, Hung-Yu Yang, Santu Baidya +11
Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect, and negative magnetore…
Two types of colossal magnetoresistance with distinct mechanisms in Eu5In2As6
Sudhaman Balguri, Mira B. Mahendru, Enrique O. Gonzalez Delgado +8
Recent reports of colossal negative magnetoresistance (CMR) in a few magnetic semimetals and semiconductors have attracted attention, because these materials are devoid of the conv…
Vanishing ordered moment in the frustrated triangular lattice antiferromagnet CuNdO
Jonathan Gaudet, Dalmau Reig-i-Plessis, Bogeng Wen +9
We investigate the magnetic ground state of CuNdO, which is a delafossite with a triangular lattice of magnetic Nd ions that are well separated by non-magnetic Cu spacer…
Stripe Helical Magnetism and Two Regimes of Anomalous Hall Effect in NdAlGe
Hung-Yu Yang, Jonathan Gaudet, Rahul Verma +11
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 h…
