Abstract: High Resolution Image Download MS PowerPoint Slide van der Waals MnPS 3 compound belonging to the class of Néel-type antiferromagnets (AFM) has recently emerged as a promising two-dimensional material for spintronic applications. In this study, we report on the electron spin resonance (ESR) study of an MnPS 3 single crystal across the Néel transition temperature ( T N = 78 K) for the magnetic field applied in the directions parallel and perpendicular to the crystallographic c axis. Furthermore, the ESR angular dependence at a temperature near T N has been investigated. We observed multiple resonance modes with antiferromagnetic, ferromagnetic, and paramagnetic characters. In addition, we revealed the occurrence of complex spin–spin correlations and a magnetic-topological Berezinskii–Kosterlitz–Thouless (BKT) phase transition (i.e., bound vortex-antivortex pairs) at T BKT with T BKT / T N typically found in two-dimensional magnets.
