Insider Brief
- A team of international researchers has reported the first definitive evidence of antiferromagnetism in a real icosahedral quasicrystal, resolving a decades-old question in condensed matter physics.
- The team used neutron diffraction to detect magnetic Bragg peaks in a novel Au-In-Eu quasicrystal, confirming the presence of long-range antiferromagnetic order below 6.5 K.
- The findings suggest that quasicrystals with positive Curie-Weiss temperatures may favor antiferromagnetic order, opening new avenues for spintronics and energy-efficient magnetic technologies.
PRESS RELEASE — Quasicrystals are intriguing materials with long-range atomic order that lack periodicity. It has been a longstanding question whether antiferromagnetism, while…
