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…

Two-component anomalous Hall and Nernst effects in anisotropic Fe $_{4 - x}$ Ge $_{x}$ N thin films

R. K. Paul, J. VÃt, P. LevinskÃ½ +18

A series of thin films Fe $_{4 - x}$ Ge $_{x}$ N (x=0-1) was fabricated onto MgO substrates by magnetron sputtering with the aim of studying the possible enhancement of the anomalous Nerns…

Fingerprints of Mott and Slater gaps in the core-level photoemission spectra of antiferromagnetic iridates

K. Nakagawa, A. Hariki, T. Okauchi +15

We present Ir $4 f$ core-level hard-x-ray photoemission spectroscopy (HAXPES) experiments conducted across antiferromagnetic (AFM) ordering transition in Ruddlesden-Popper iridates…
