هنگامی که در معرض هوا قرار می گیرد، نانومواد جدید در دماهای بالا مغناطیسی می شوند

When exposed to air, new nanomaterial becomes magnetic at high temperatures

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."
