Magnon-phonon hybridization in 2D antiferromagnet MnPSe ₃

Abstract

Strong hybridization of two-magnon scattering with phonons is observed in 2D antiferromagnet MnPSe 3 .

Photoluminescence Enhancement by Band Alignment Engineering in MoS2/FePS3 van der Waals Heterostructures

“…In the past decade, two-dimensional (2D) crystals have attracted the attention of a broad community of chemists, physicists, and material scientists due to their novel mechanical, electrical, and optical properties when thinned down to just a few atomic layers. − The direct gap and photoluminescent properties of single-layer 2H TMDs have facilitated their use as the active media of optoelectronic devices. ,− Recently, a growing interest in a new family of 2D compounds has emerged, namely the transition metal chalcogenophosphates, with the general formula MPX 3 (where M is a transition metal, P is phosphorus, and X is a chalcogen). MPX 3 s have been explored in terms of their antiferromagnetic phase transition, − photo-response, − and promising applications in spintronics. − …”

Exploring Vibrational Spectroscopy of Quantum Materials in the Scanning Transmission Electron Microscope

“…This study plans to expand the list of studied materials to include MnPSe 3 , a two-dimensional material with antiferromagnetic ordering below 74 K, the structure of which is shown in Figure 2. MnPSe 3 has several Raman-active phonon modes which this study will experimentally demonstrate are also observable with STEM-EELS [5].…”

“…Due to the antiferromagnetic ordering, MnPSe 3 also hosts magnon modes. A recent study using magneto-Raman spectroscopy observed magnon-phonon coupling between a two-magnon excitation and two E g phonons [5]. This study further plans to explore the effect of magnon-phonon coupling on the observable phonon peaks in the EELS low-loss spectrum.…”

An effective field theory of magneto-elasticity

“…We will finally turn our attention to the coupled system of phonons and magnons. Magnetoelastic effects have already been studied in ferromagnets [9,[43][44][45][46], ferrimagnets [47], and antiferromagnets [48][49][50]. However, the focus has been on particular effects (e.g.…”
