2-D materials are atomically thin, single-layered films arranged in a crystal structure, which have potential applications in next-generation electronics and optoelectronic devices. Ferromagnetism (FM) in such materials ‒ the mechanism by which they act as magnets ‒ was considered implausible until a few years ago. In 2017, scientists discovered low-temperature FM in 2-D materials, which has led to significant advances in the fields of nanotechnology and electronics.
