Published in 2020 at "ACS applied materials & interfaces"

DOI: 10.1021/acsami.0c08024

Abstract: Nanoscale, low-phase noise, tunable transmitter-receiver links are key for enabling the progress of wireless communication. We demonstrate that vortex-based spin-torque nano-oscillators, which are intrinsically low-noise devices due to their topologically-protected magnetic structure, can achieve frequency… read more here.
