Abstract

We report on magnetotransport properties associated with the all-in-all-out magnetic order for Tb2Ir2O7 single-crystalline thin films. Two degenerate all-in-all-out domains of an Ir sublattice can be switched to each other by magnetic field along the [111] direction as detected by a characteristic magnetoresistivity with diplike hysteresis. For a given single-domain structure, the linear magnetoresistivity, reflecting the effective magnetic field at Ir4+, changes its sign at around 70 K. These observations are consistently explained by the molecular fields from Tb3+ on Ir4+ moments. The molecular fields from Tb3+ moments compete with the external fields and dominate the magnetoresponse of Ir4+ moments at lower temperature, whereas the external field does at higher temperature.
