Synthesis of Two-Dimensional Antiferromagnetic Semiconductor CuFeS<sub>2</sub> with a High Néel Temperature

Two-dimensional (2D) antiferromagnetic (AFM) semiconductors have garnered significant attention due to their promising applications in spintronics and intriguing magneto-optical performance. However, low Néel temperatures (<i>T</i><sub>N</sub>) and inadequate air stability constrain their application. Here, we report the synthesis of a 2D semiconducting CuFeS<sub>2</sub> (CFS) exhibiting AFM order. It features a high <i>T</i><sub>N</sub> (473.0 ± 0.4 K) and remains stable in air for at least 2 weeks. The semiconductor characteristics are confirmed via electrical measurements. AFM order and a high magnetic phase transition temperature are demonstrated by Raman and second-harmonic generation (SHG) spectra. This work provides a new 2D AFM semiconductor with a high Néel temperature, offering a novel platform for studying unconventional physical phenomena and spintronics.

Abstract

Two-dimensional (2D) antiferromagnetic (AFM) semiconductors have garnered significant attention due to their promising applications in spintronics and intriguing magneto-optical performance. However, low Néel temperatures (<i>T</i><sub>N</sub>) and inadequate air stability constrain their application. Here, we report the synthesis of a 2D semiconducting CuFeS<sub>2</sub> (CFS) exhibiting AFM order. It features a high <i>T</i><sub>N</sub> (473.0 ± 0.4 K) and remains stable in air for at least 2 weeks. The semiconductor characteristics are confirmed via electrical measurements. AFM order and a high magnetic phase transition temperature are demonstrated by Raman and second-harmonic generation (SHG) spectra. This work provides a new 2D AFM semiconductor with a high Néel temperature, offering a novel platform for studying unconventional physical phenomena and spintronics.
