Altermagnetism and Weak Magnetism in the Insulating Distorted Perovskite Antiferromagnet NaOsO${}_3$

Hong-Suk Choi, M. -C. Jung, K. -H. Ahn +2

The GdFeO${}_3$-type perovskite antiferromagnet NaOsO${}_3$, calculated here to be altermagnetic for all three typical collinear antiferromagnetic orders, was suggested early on to be…
