Hitachi High-Tech employee, Takeshi Sato, collaborated with a research group headed by Assistant Professor Yuki Kimura of the Graduate School of Science at Tohoku University and Researcher Kazuo Yamamoto of the Japan Fine Ceramics Center(JFCC), and a paper by this research group was published on the October 22, 2013 issue of "Nature Communications".
Utilizing the holographic electron microscope Hitachi HF-3300EH at JFCC, the research group observed some magnetite nanoparticles contained in meteorites. The holography imaging identified a vortex magnetic domain structure.
The outcome of this research contributes to a breakthrough discovery for how minerals are generated on an asteroid in early phase of the solar system.
