Spin-orbit-entangled magnetism and unconventional spin freezing in the bond-disordered pyrochlore antiferromagnet NaCdCoF
Andrej Kancko, Hironori Sakai, Javier Herrero-MartÃn +5
Bond disorder in frustrated pyrochlore antiferromagnets can give rise to fundamentally different quantum ground states depending on the nature of the local magnetic moments. Here,…
Electrical and thermal magnetotransport in altermagnetic CrSb
Sajal Naduvile Thadathil, Christoph Müller, Reza Firouzmandi +20
Chromium antimonide has emerged as a key material platform for studying altermagnetism because of its simple binary composition, high Néel temperature, and semimetallic electronic…
Fermi-surface studies of altermagnetic CrSb from Shubnikov-de Haas oscillations
Sajal Naduvile Thadathil, Beat Valentin Schwarze, Jaafar Ansari +13
Within the family of altermagnets, CrSb is a metallic, collinearly ordered material that exhibits particularly strong symmetry-induced spin splitting in its band structure. In this…
Random singlet physics in the pyrochlore antiferromagnet NaCdCuF
Andrej Kancko, Hironori Sakai, Cinthia Antunes Corrêa +7
We report a random singlet ground state in the Heisenberg pyrochlore antiferromagnet NaCdCuF. Cationic Na/Cd disorder on the pyrochlore site…
Direct probe of magnetic field effects on phonons by ultrasound propagation in a quasi-two-dimensional honeycomb magnet NaCoTeO
Xiaochen Hong, Maximilian Schiffer, Beat Valentin Schwarze +9
We study the phonon behavior of a Co-based honeycomb frustrated magnet NaCoTeO under magnetic field applied perpendicular to the honeycomb plane. The temperature and fi…
Coexistence of anomalous spin dynamics and weak magnetic order in a chiral trillium lattice K2FeSn(PO4)3
J. Khatua, S. Krishnamoorthi, Changhyun Koo +13
Trillium lattices, where magnetic ions form a three-dimensional chiral network of corner-sharing equilateral triangular motifs, offer a prominent platform to explore exotic quantum…
