Author(s): Shovan Gayen, Sk. Soyeb Ali, and S. K. Panda We combine first-principles density-functional theory, Berry-curvature analysis, semiclassical Boltzmann transport, and atomistic spin dynamics to establish hexagonal NiS as a compensated $3d$ altermagnetic semimetal in which topology, magnetism, and lattice dynamics are intrinsically intertwined.
