Electronic Correlations Control Interlayer Coupling and Magnetic Transition in MnBi$_2$Te$_4$/MnBr$_3$ Heterostructure
DFT and Monte Carlo calculations predict that MnBi2Te4/MnBr3 heterostructures raise the MnBi2Te4 Curie temperature to 72 K when the Hubbard U in MnBr3 is 3 eV, with coupling strength controlled by U-driven structural distortions.
