Antiferromagnetic domain distribution is analyzed by a scanning superconducting quantum interference device microscopy for a pyrochlore Tb2Ir2O7 thin film with an all-in-all-out (AIAO) spin arrangement. The local magnetic field on the surface is found to originate predominantly from the Tb3+(J=6) magnetic moment. While Ir4+ magnetic moment (Jeff=1/2) is too small to detect even below the Néel temperature (120 K), Tb3+ AIAO domains grow below 40 K following the background Ir4+ domains rather than the external magnetic field, clarifying the decisive role of Ir-Tb exchange interaction in magnetic ordering.
