Topological Weyl and Node-Line Semimetals in Ferromagnetic Vanadium-Phosphorous-Oxide $\beta$-V${}_2$OPO${}_4$ Compound

Y. J. Jin, R. Wang, J. Z. Zhao +3

We propose that the topological semimetal features can co-exist with ferromagnetic ground state in vanadium-phosphorous-oxide $\beta$-V${}_2$OPO${}_4$ compound from first-principles calcul…
