Robust pinning of magnetic moments in pyrochlore iridates
Pyrochlore iridates ${A}_{2}{\mathrm{Ir}}_{2}{\mathrm{O}}_{7}$ ($A$ = rare earth elements, Y or Bi) hold great promise for realizing novel electronic and magnetic states owing to the interplay of spin-orbit coupling, electron correlation, and geometrical frustration. A prominent example is the formation of all-in/all-out (AIAO) antiferromagnetic order in the ${\mathrm{Ir}}^{4+}$ sublattice that comprises …
