Magnetic materials displaying what is referred to as itinerant ferromagnetism are in an elusive physical state that is not yet fully understood. They behave like a magnets under very specific conditions,such as at ultracold temperatures near absolute zero. Physicists normally gain no other choice than to study this very unique state of matter in a controlled fashion, using ultracold atomic gases. Now, and a team based at ETH Zurich,Switzerland has introduced two current theoretical approaches to stabilise the ferromagnetic state in quantum gases to help study the characteristics of itinerant ferromagnetic materials. These results were recently published in EPJ B by Ilia Zintchenko and colleagues.
