Theoretical calculations for the Curie temperature in TMD Janus systems. (a) Diagram of the VSeTe crystal structure in top-down and cross-sectional views. (b) Temperature-dependent magnetic moment and specific heat of VSeTe, obtained via Monte Carlo simulations in a nearest-neighbor Heisenberg exchange model.
