Owing to comparably strong spin-orbit coupling and Hubbard interaction, iridium based 227 pyrochlore oxides harbor a rich confluence of competing magnetic orders and emergent multipolar Weyl quasiparticles. Here we show that this family of materials is predominantly susceptible toward the nucleation of electronic noncoplanar all-in all-out (AIAO) and three-in one-out (3I1O) orders, respectively transforming under the singlet A2u and triplet T1u representations, supporting octupolar and dipolar…

Weyl-Luttinger phase transition in pyrochlore iridates revealed by Raman scattering

Pyrochlore iridates are thought to be a fertile ground for the realization of topologically non-trivial and strongly correlated states of matter. Here we provide a compelling evidence of interacting

Recent DFT+DMFT calculation suggests that such an insulator is topologically trivial at high temperatures

  • For sufficiently large magnetic order the Weyl points can be pushed out of the Brillouin zone and the system then becomes a T breaking insulator
