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 magnet Cu2OSeO3 can emerge due to the spin noncollinearity induced by antiferromagnetic cantings. Type II multiferroics like this may pave the way for the next generation of advanced electronics, as their properties can be altered using applied fields.
