Abstract

Recent advances in the synthesis of intercalated compounds have opened new avenues for exploring novel magnetic properties. This work focuses on the synthesis of high-quality single crystals of NbCo_1.1Te₂, achieved through a meticulously optimized chemical vapor transport method that facilitates effective cobalt intercalation into the van der Waals gaps of NbCoTe₂. Comprehensive characterizations, including magnetic susceptibility, angle-resolved photoemission spectroscopy (ARPES), and magnetoresistance measurements, revealed pronounced room-temperature ferromagnetism and significant magnetic anisotropy, along with a confirmed metallic nature of NbCo_1.1Te₂. These findings underscore the transformative effects of cobalt intercalation on the physical properties of NbCo_1.1Te₂, demonstrating its promising potential for advanced electronic and spintronic applications, and laying the groundwork for future research on related materials.
