Outline explanation
In the past, electron microscopes basically place a sample in a strong magnetic field. The structure of the magnet and steel is broken by the magnetic field. Therefore, observation of atomic structure is difficult.
Newly devised lens that hits the heart of the microscope (patent pending). Succeeded in direct observation of the atomic structure of the electrical steel sheet, with only the magnetic field applied to the sample being almost zero.
It is expected to be an advanced measurement instrument that is indispensable for research and development of superior magnetic materials such as permanent magnets, electromagnetic steel sheets, and high density magnetic recording media used in electric vehicles.
Development this time: A new electron microscope
With the exception of the objective lens, it can be used in the same way as a conventional electron microscope.
Significant progress in nanotechnology research and development.
The project is jointly conducted with Monash University in Australia.
The development results will be published on May 24, 2019 in the online version of the British science magazine “Nature Communications”.
