ECE Seminar: "Current-induced THz-frequency Magnetization Dynamics in Antiferromagnettic Crystals," Andrei Slavin, Oakland University, Rochester, MI

August 17 @ 1:00 pm - 2:00 pm

Speaker: Andrei Slavin, Oakland University, Rochester, MI Title: Current-induced THz-frequency Magnetization Dynamics in Antiferromagnettic Crystals Abstract: Antiferromagnetic (AFM) materials have natural resonance frequencies in the sub-THz to THz frequency range. Thus, it is tempting to use antiferromagnets as active layers in THz-frequency spin-torque nano-oscillators (STNOs). However, a familiar mechanism of spin-transfer torque (STT) damping compensation used in ferromagnetic (FM) STNOs [1] does not work for the AFM materials. In the AFM two magnetic sublattices are aligned anti-…
