Tokyo, July 4, 2024 --- Hitachi, Ltd. (TSE: 6501, Hitachi), Kyushu University, RIKEN, and HREM Research Inc. (HREM) today announced the world's first observation of magnetic fields of individual lattice planes.*1 This was achieved by using Hitachi's atomic-resolution holography electron microscope and a method enabling magnetic field observation of samples with uneven structures and compositions (hereinafter referred to as non-uniform samples)*2 such as magnetic multilayer films, which have been difficult to observe so far, in collaboration with National Institute of Advanced Industrial Science and Technology (AIST) and National Institute for Materials Science (NIMS). Observation was accomplished by developing a technology with a higher degree of electron-holography precision and automated post-image-capture focus correction. With this, it is now possible to observe magnetic fields of the atomic-layer level at local boundaries between materials (interfaces), which greatly affe
