The magnetic properties of materials are caused by a characteristic of their electrons known as spin. When a number of atoms carrying electronic spins come together they can form nanoscale units with a unique magnetic nature. In particular, quantum mechanical effects are enhanced by the finite size of magnetic nanostructures, and profoundly affect the motion of spins.
In this new experiment, scientists fired a beam of neutrons at a sample containing these nanoscale units….
