Ultrafast Exchange Interaction hinted at in Ferromagnetic and Antiferromagnetic Spin Reversal

A paper titled “Transient ferromagnetic-like state mediating ultrafast reversal of antiferromagnetically coupled spins”, submitted last September, has finally made it into Nature Letters, and shows some promise for increasing the reach of spin computing speed, particular to the exchange interaction between Gadolinium, Cobalt, and Iron: …We use the element-specific technique X-ray magnetic circular dichroism to […]
