Abstract

In recent years, the rapid development of two-dimensional (2D) magnetic materials has revolutionized the field of spintronics, driven by their unique ability to combine magnetism and electronic functionality at the atomic scale. Here, we investigate the monolayer CuCr2Se2X2(X = Cl, Br, I), which exhibit robust ferromagnetic (FM) behavior and half-metallicity with 100% spin polarization. The strong FM coupling, mediated by superexchange interactions, is rooted in the unique electronic structure of the Crd-orbitals. Our findings reveal high Curie temperatures (TC) exceeding room temperature, with the Br variant achieving a remarkable 586 K. These exceptional properties, including the ability to modulate exchange interactions through strain engineering, highlight CuCr2Se2X2as a versatile platform for flexible, high-performance spintronic devices, paving the way for advancements in next-generation electronic applications.

期刊介绍: Journal of Physics: Condensed Matter covers the whole of condensed matter physics including soft condensed matter and nanostructures. Papers may report experimental, theoretical and simulation studies. Note that papers must contain fundamental condensed matter science: papers reporting methods of materials preparation or properties of materials without novel condensed matter content will not be accepted.
