While known for a long time, antiferromagnetically ordered systems have previously been considered, as expressed by Louis Néel in his Nobel Prize Lecture, to be “interesting but useless”. However, since antiferromagnets potentially promises faster operation, enhanced stability with respect to interfering magnetic fields and higher integration due to the absence of dipolar coupling, they could potentially become a game changer for new spintronic devices.
We recently realized switching in the metallic antiferromagnet Mn<sub>2</sub>Au by intrinsic staggered spin-orbit torques [1,2] and characterize the switching properties by direct imaging. While switching by staggered intrinsic spin-orbit torques in metallic AFMs requires special structural asymmetry, interfacial non-staggered spin-orbit torques can switch multilayers of many insulating AFMs capped with heavy metal layers [3-5]. Furthermore electric fields can be used to generate strain to switch the AFM order parameter [6].
To read out the information, we demonstrate that we can obtain ultra-strong coupling from AFMs to ferromagnetic layers.
