Robust pinned magnetisation in A₂Ir₂O₇ iridates, the case of Er₂Ir₂O₇ and Lu₂Ir₂O₇ flux-grown single crystals.

ABSTRACT: In addition to complex spin-ice and spin-liquid states of rare-earth pyrochlore oxides, A₂Ir₂O₇ iridates have been recently proposed to host a cooling-field-controllable antiferromagnetic domain structure of iridium moments. Reliable and profound studies of the magnetic domain structure, including domains' interfaces, have been frequently limited by insufficient sample quality or lack of single crystals. We report the magnetic properties of the for-the-first-time synthesised Lu₂Ir₂O₇ and Er₂Ir₂O₇ single crystals; focussing on the robust ferromagnetic component of magnetisation present in the material with the antiferromagnetically ordered state of the all-in-all-out (AIAO) type.
