| contents | Antiferromagnetic (AF) compounds possess distinct characteristics that render them promising candidates for advancing the application of spin degrees of freedom in computational devices. For instance, AF materials exhibit minimal susceptibility to external magnetic fields while operating at frequencies significantly higher than their ferromagnetic counterparts. However, despite their potential, there remains a dearth of understanding, particularly concerning certain aspects of AF spintronics. In particular, the properties of coherent states in AF materials have received insufficient investigation, with many features extrapolated directly from the ferromagnetic scenario. Addressing this gap, this study offers a comprehensive examination of AF coherent states, shedding new light on both AF and Spin-Flop phases. Employing the Holstein-Primakoff formalism, we conduct an in-depth analysis of resonating-driven coherent phases. Subsequently, we apply this formalism to characterize antiferromagnetic resonance, a pivotal phenomenon in spin-pumping experiments, and extract crucial insights therefrom. |
