Abstract:

Recently, antiferromagnets (AFMs) are shown to be promising candidates for next-generation spintronic materials, as they hold potential to replace ferromagnets based on three salient features: 1) AFMs typically operate at Terahertz frequency. 2) AFMs bear a unique degree of freedom that refers to the chirality of spin wave. 3) AFMs have vanishing magnetization which helps in stabilizing and scaling down a magnetic device. In this talk, I will introduce recent progress in understanding these crucial properties of AFMs as well as their possible applications. I will discuss electrical, optical, thermal, and mechanical effects that are uniquely associated with antiferromagnets, which might be useful to create multifunctional Terahertz magnetic devices with low dissipation.
