Image of the week: magnetic structure of Cu2OSeO3

By Tom Sharp on March 27, 2017

This weeks image come from a recent Journal of Physics: Condensed Matter paper by Viacheslav Chizhikov and Vladimir Dmitrienko. They theoretically investigated the cause of ferroelectric behaviour in the chiral magnet Cu2OSeO3. They found that Ferroelectric properties of cubic chiral… Read More ›
