First Bulk Ferromagnetic Icosahedral Quasicrystals Synthesized without Rapid Quenching
Researchers at the Tokyo University of Science have successfully synthesized bulk ferromagnetic icosahedral quasicrystals without using rapid quenching. This breakthrough allows for the first systematic study of intrinsic magnetic properties in these complex materials.
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 ten-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.
