The creation of a new magnetic molecule could pave the way to build new, stamp-sized hard drives capable of holding the equivalent of 40,000 CDs' worth of music—that's three years of nonstop tunes!

Single-molecule magnets can store information individually and don't need help from their neighbors to retain their memory, offering the potential for ultra-high data densities.
