Abstract Layered van der Waals magnetic chalcogenides provide an important platform for exploring the interplay between lattice dynamics and magnetic correlations in low-dimensional systems. Here, we present a comprehensive temperature-dependent Raman spectroscopy study of a layered antiferromagnetic semiconductor MnSi2Te4, which exhibits large negative magnetoresistance. Several Raman modes exhibit pronounced and mode-selective anomalies in frequency, linewidth, and intensity near the antiferromagnetic Néel temperature (18.6 K) and a possible hidden phase transition temperature (100 K), whereby deviations from Curie-Weiss behavior in magnetic susceptibility were previously reported. Angle-resolved polarized Raman spectroscopy (ARPRS) measurements reveal distinct polarization-dependent responses for different Raman modes. These results indicate a nontrivial coupling between lattice vibrations and magnetic ordering in MnSi2Te4, and demonstrate Raman spectroscopy as an effective probe of structural phase transition and spin-lattice coupling in van der Waals magnets.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
