Abstract
1T-phase CrTe2 (1T-CrTe2) has received considerable interest recently due to its high Curie temperature (TC), which is desirable for practical spintronics applications. However, various magnetic behaviors of 1T-CrTe2 have been reported in recent experimental and theoretical studies when its thickness reduces to ultrathin limit. In this work, the magnetic diagram of monolayer (ML) 1T-CrTe2 with respect to in-plane biaxial strain and on-site Coulomb repulsion U is obtained based on first-principles calculations. Our results indicate that the magnetic order of ML 1T -CrTe2 can vary among ferromagnets and antiferromagnets with strain and electronic correlation. We show that the large exchange anisotropy and higher-order biquadratic interactions are crucial to accurately describe the spin energies in ML 1T-CrTe2. The perplexing dependencies of the magnetocrystalline anisotropy on strain and U are then well explained. Our work not only gives insight into the fundamental understanding of the unusual magnetic properties of ML 1T-CrTe2, which is helpful to understand the diverse observations on the magnetic order in CrTe2, but also sheds light on engineering their performance for spintronic devices.
