When exposed to air, new nanomaterial becomes magnetic at high temperatures
Researchers have synthesized a new nanomaterial using silver, chromium, and selenium that exhibits a significant increase in magnetic stability when exposed to air. The material maintains magnetism at temperatures up to 400 Kelvin, a major improvement over its original state.
Why it matters
This discovery could lead to advancements in quantum information science and fiber optic technology by providing more robust magnetic materials.

DOI: 10.1021/jacs.6c09346 While fridge magnets are great for saving favorite recipes, modern magnetic materials are useful for improving fiber optics or quantum information science technology. On most fridge magnets the atoms are arranged in a repeated lattice structure called a "spinel." These structures are made up of three types of atoms, generically referred to as atoms "A," "B" and "X."
