N2 - Physical properties of U3Si2 with non-magnetic, ferromagnetic, and antiferromagnetic structures are predicted using DFT+U with Hubbard-U values from 0 to 4 eV. The stability of U3Si2 is compared with its neighbouring phases, U3Si and USi. The results emphasize the importance of magnetism. For non-magnetic U3Si2 a very large Hubbard-U value is required to accurately reproduce the physical constants. However, from the electronic structure of the studied magnetic states withdifferent Hubbard-U values, it is clear that it is incorrect to use a non-magnetic model for paramagnetic U3Si2 because of the resulting nearly zero occupation of f-electrons.
