Magnon Gap Excitations in 2D Antiferromagnets

Abstract

The study of magnon gap excitations in two-dimensional (2D) antiferromagnets is a crucial aspect of spintronics and quantum information technologies. These excitations, arising from the energy gap between the ground state and excited states, play a vital role in the manipulation and control of spin-based phenomena. This paper explores the underlying mechanisms of magnon gap formation in 2D antiferromagnetic materials, with particular emphasis on their potential applications in low-power electronics and quantum devices. We review theoretical models, experimental observations, and recent advancements in the field, highlighting the unique properties of 2D antiferromagnets compared to their bulk counterparts. We also provide an in-depth analysis of the future prospects for magnonic devices based on 2D antiferromagnetic materials
