Description:

Atomic-scale observations in a desired local area should bring a great benefit to exploring novel fundamental materials and devices. Developments of hardware-type aberration corrector1,2 in electron microscopy have enabled atomic resolution in local structural observations3-5, chemical6,7, and vibration analysis8. As for magnetic imaging, however, atomic-level spin configuration has only been analyzed by electron energy-loss spectroscopy with placing samples in strong magnetic fields9-11, which destroys the nature of the magnetic ordering in samples. Here, we report that the magnetic fields inside materials can be observed at atomic resolution under magnetic-field-free conditions by electron holography with a hardware-type aberration-corrector assisted by post digital aberration corrections. Magnetic-field distributions of atomic-layer period formed by opposite magnetic moments of Fe and Mo atoms in a double-perovskite structured ferrimagnet (Ba2FeMoO6) are successfully resolved. This capability opens the door to studies of materials and devices by atomic-resolution magnetic-field observations of local areas such as interfaces and grain boundaries.
