"Breakthrough Discovery: Unveiling a Novel Form of Magnetism with Unique Magnetic Alignment"
Scientists at ETH Zurich have discovered a new type of magnetism in a custom-engineered moiré material. Unlike traditional ferromagnetism, this magnetism arises from the alignment of electron spins to minimize kinetic energy rather than the exchange interaction. The researchers filled the material with electrons and observed that it exhibited ferromagnetic behavior when there was more than one electron per lattice site. This phenomenon, known as kinetic magnetism, had previously only been observed in model systems and not in extended solid-state systems. Further research will explore the preservation of ferromagnetism at higher temperatures.
