DOI: 10.1002/adma.202206941
Abstract: Magnetic topological semimetals provide new opportunities for power generation and solid‐state cooling based on thermoelectric (TE) effect. The interplay between magnetism and nontrivial band topology prompts the magnetic topological semimetals to yield strong transverse TE… read more here.

DOI: 10.1038/nmat4987
Abstract: Weyl fermions have been observed as three-dimensional, gapless topological excitations in weakly correlated, inversion-symmetry-breaking semimetals. However, their realization in spontaneously time-reversal-symmetry-breaking phases of strongly correlated materials has so far remained hypothetical. Here, we report experimental… read more here.

DOI: 10.1103/physrevb.101.064514
Abstract: Magnetic Weyl semimetals (WSMs) have been presumed to be immune to proximity-induced spin-singlet superconducting pairing due to a chirality blockade of the regular Andreev reflection. In this work we study all possible superconducting pairing induced… read more here.

DOI: 10.1103/physrevb.102.035155
Abstract: Using both an effective three-band model and ab initio calculations, we have investigated various topological features in the cubic ferromagnetic $5{d}^{1,2}$ systems showing large spin-orbit coupling (SOC): ${\mathrm{Ba}}_{2}{\mathrm{NaOsO}}_{6}, {\mathrm{Sr}}_{2}{\mathrm{SrOsO}}_{6}$, and ${\mathrm{Ba}}_{2}B{\mathrm{ReO}}_{6}$ ($B$=Mg, Zn). In the… read more here.

DOI: 10.1103/physrevb.104.024414
Abstract: We analyze the decay of spin waves into Stoner excitations in magnetic Weyl semimetals. The lifetime of a mode is found to have a universal dependence on its frequency and momentum, and on a few… read more here.

Abstract: Co3Sn2S2 is a magnetic Weyl semimetal, in which ferromagnetic ordering at 177K is predicted to stabilize Weyl points. We perform temperature and spatial dependent angle–resolved photoemission spectroscopy measurements through the Curie temperature (Tc), which show… read more here.

Abstract: Magnetic Weyl semimetals Weyl semimetals (WSMs)—materials that host exotic quasiparticles called Weyl fermions—must break either spatial inversion or time-reversal symmetry. A number of WSMs that break inversion symmetry have been identified, but showing unambiguously that… read more here.
