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 […]

Nanoscale Thermoelectric Peltier cooling in Graphene

Thermoelectric peltier cooling effects at graphene and metal junctions have been demonstrated by a group out of the University of Illinois. Kyle Grosse, Feifei Lian, Myung-Ho Bae,William King, and Eric Pop used “… atomic force microscopy to measure the temperature distributions at the contacts of working graphene transistors”: Our data indicate that thermoelectric effects account […]
