Lattice Reconstruction and Orbital Hybridization Suppress Magnetism in TaCoTe

Ulysse Chazarin, Bharat C. Bathu, Zuned Ahmed +6

Structural reconstruction in low-dimensional quantum materials can strongly modify electronic symmetry and magnetic stability through orbital hybridization. Here, we investigate th…

Robust spin splitting and fermiology in a layered altermagnet

Alessandro De Vita, Chiara Bigi, Davide Romanin +42

Altermagnetism defies conventional classifications of collinear magnetic phases, standing apart from ferromagnetism and antiferromagnetism with its unique combination of spin-depen…

Spin-degenerate bulk bands and topological surface states associated with Dirac nodal lines in RuO2

T. Osumi, K. Yamauchi, S. Souma +13

Altermagnets are a novel platform to realize exotic electromagnetic properties distinct from those of conventional ferromagnets and antiferromagnets. We report results of micro-foc…

Uncovering surface states of the Dirac semimetal BaMg2Bi2

A. De Vita, J. Bakkelund, H. ŚwiÄ tek +13

BaMg2Bi2 is a Dirac semimetal characterized by a simple Dirac cone crossing the Fermi level at the center of the Brillouin zone, protected by C3 rotational symmetry. Together with…

Discovery of magnetic-field-tunable density waves in a layered altermagnet

Christopher Candelora, Muxian Xu, Siyu Cheng +11

Altermagnets recently came into the spotlight as a new class of magnetic materials, arising as a consequence of specific crystal symmetries. They are characterized by a spin-polari…

Anomalous spin-optical helical effect in Ti-based kagome metal

Federico Mazzola, Wojciech Brzezicki, Chiara Bigi +32

The kagome lattice stands as a rich platform for hosting a wide array of correlated quantum phenomena, ranging from charge density waves and superconductivity to electron nematicit…
