Magnetic structure evolution of the Nd2Ir2O7 pyrochore iridate through its field induced insulator to semimetal transition
Pyrochlore iridates with formula A2Ir2O7 (A = rare earth) have attracted a lot of attention in the past decade due to comparable energy scales associated with crystal field, electronic correlations and spin-orbit coupling, which give rise to a very rich physics. Very recently, magneto-resistivity measurements performed on Nd2Ir2O7 showed that this material exhibits a field induced insulator to semimetal quantum phase transition around 10 T when the field is applied along the [100] direction. This intriguing transition is understood theoretically by the change of magnetic structure of the Nd sublattice from All-in-All-out (AIAO) to 2-in-2-out magnetic structure; the later affecting drastically the band structure of the Ir sublattice through f-d exchange coupling. While understood theoretically, this statement however, has not been confirmed experimentally. Our experiment intends to tackle this issue by performing a neutron diffraction experiment on an Nd2Ir2O7 single crystal under magnetic field.
