Altermagnetism and Weak Magnetism in the Insulating Distorted Perovskite Antiferromagnet NaOsO
Hong-Suk Choi, M. -C. Jung, K. -H. Ahn +2
The GdFeO-type perovskite antiferromagnet NaOsO, calculated here to be altermagnetic for all three typical collinear antiferromagnetic orders, was suggested early on to be…

Pressure effects on the electronic structure and magnetic properties of infinite-layer nickelates
Shekhar Sharma, Myung-Chul Jung, Harrison LaBollita +1
Motivated by the discovery of superconductivity in infinite-layer nickelates RNiO (R= rare-earth), and the subsequent enhancement of their T with pressure, we investigate t…

Symmetry Enforced Fermi Surface Degeneracies Observed in Time-Reversal Symmetry-Breaking Superconductor LaNiGa
Matthew Staab, Robert Prater, Sudheer Sreedhar +11
LaNiGa is superconductor that breaks time-reversal symmetry in the superconducting state without any known nearby magnetism. Recently, single crystals of LaNiGa have been s…
