Successful observation of a magnetic field with the world's highest resolution of 0.67nm using an atomic-resolution holography electron microscope
Hitachi and RIKEN today announced the development of technology to improve observation precision using Hitachi's atomic-resolution holography electron microscope, and the successful observation of magnetic field distributions within magnetic multilayer materials at a world's highest resolution of 0.67nm.
This technology enables the observation of the magnitude and direction of magnetic fields that are related to the properties of highly-functional materials, such as permanent magnets, electromagnetic steel sheets, and magnetic thin films, at a level of few atoms at the boundary of the material.
Hitachi and RIKEN are looking to contribute to the development of highly functional materials such as high-performance magnets and high-temperature superconducting materials, and progress in fundamental science, by elucidating atomic-scale magnetic phenomena.
