Mechanism for the Broadened Linewidth in Antiferromagnetic Resonance

The linewidth of antiferromagnetic resonance (AFMR) is found to be significantly broader than that of ferromagnetic resonance (FMR), even when the intrinsic Gilbert damping parameter is the same for both systems. We investigate the origin of this enhanced damping rate in AFMR by studying a bipartite...

description The linewidth of antiferromagnetic resonance (AFMR) is found to be significantly broader than that of ferromagnetic resonance (FMR), even when the intrinsic Gilbert damping parameter is the same for both systems. We investigate the origin of this enhanced damping rate in AFMR by studying a bipartite magnet model. Through analytical calculations and numerical simulations, we present three perspectives on understanding this linewidth broadening in AFMR: i) The non-dissipative Heisenberg exchange interaction develops a damping-like component in the presence of Gilbert damping, ii) The transverse component of the exchange coupling reduces the AFMR frequency, thereby increasing the damping rate, and iii) The antiferromagnetic eigenmode exhibits characteristics of a two-mode squeezed state, which is inherently linked to an enhanced damping rate. Our findings provide a comprehensive understanding of the complex dynamics governing magnetic dissipation in antiferromagnet and offer insights into the experimentally observed broadened linewidths in AFMR spectra.
