A publication from the team of antiferromagnetic spintronics about giant and tunneling magnetoresistance in unconventional collinear antiferromagnets has been published in Physical Review X.
They presentc archetype model mechanisms for the giant and tunneling magnetoresistance effects in multilayers of such materials. These mechanisms are linked to real materials through ab-initio calculations. Further they show how their models can allow for magnetic excitations by teh spin transfer torque.
