AI Article Synopsis
- * Researchers conducted electron spin resonance (ESR) experiments on MnPS single crystals near the Néel transition temperature of 78 K, analyzing its behavior under different magnetic field orientations.
- * The results revealed various resonance modes with differing magnetic characteristics and indicated complex spin correlations, alongside a magnetic-topological transition involving vortex-antivortex pairs in the material.
Article Abstract
van der Waals MnPS 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 single crystal across the Néel transition temperature ( = 78 K) for the magnetic field applied in the directions parallel and perpendicular to the crystallographic axis. Furthermore, the ESR angular dependence at a temperature near 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 with / typically found in two-dimensional magnets.
