AI Insight
Researchers have successfully created bulk ferromagnetic quasicrystals without using rapid quenching methods, representing a significant advancement in magnetic materials science. Ferromagnetism has now been demonstrated in gold-based icosahedral quasicrystals, which possess unique quasiperiodic atomic arrangements and unconventional rotational symmetries like 10-fold symmetry. This establishes quasicrystals as a third distinct platform for studying magnetism, alongside traditional periodic crystals and amorphous materials.
Why it matters
The ability to produce stable ferromagnetic quasicrystals without rapid quenching enables more reliable and reproducible magnetic studies of these materials. This opens new avenues for understanding magnetism in non-periodic structures and could lead to novel magnetic materials with unique properties derived from their quasiperiodic order.
Understand the Science
Ferromagnetism has long been studied in a wide range of periodic crystals and amorphous materials. In quasicrystals (QCs), which possess long-range quasiperiodic order and unconventional rotational symmetries, such as 10-fold symmetry, ferromagnetism remained elusive until recently, when it was finally realized in gold (Au)-based icosahedral QCs. These discoveries establish QCs as a third platform for magnetism beyond periodic crystals and amorphous materials.
