From Narrow-gap Semiconductor to Metallic Altermagnet: Optical Fingerprints of Co-Doped FeSb2
R. Mathew Roy, M. Povolotskiy, J. Kirschke +11
The realization of bulk metallic altermagnetism has remained elusive despite the growing number of candidate materials. Here, we present evidence that moderate cobalt substitution…

Emergent superconductivity at 16.3 K in an altermagnetic candidate NaVSeO with broken inversion symmetry
Y. Sun, Z. Yin, T. Zhang +14
Altermagnets (AMs), characterized by zero net magnetization and momentum-dependent spin splitting, are anticipated to hold significant potential for generating multiple exotic and…

From two dimensions to wire networks in a dice-lattice Josephson array
J. D. Bondar, L. Banszerus, W. Marshall +5
We investigate Josephson arrays consisting of a dice-lattice network of superconducting weak links surrounding rhombic plaquettes of proximitized semiconductor. Josephson coupling…
