      a DFT level, because of iridium. <br>

                  <div dir="auto">I am working on a strongly
                    spin-orbital coupled d^5 system, SrIrO3
                    (orthorhombic). It's a Dirac semimetal with weakly
                    correlated (U=0.3-0.4 eV) non-magnetic ground state.
                    With GGA+U, for U=1eV, the system is showing a
                    magnetic metal phase but with LDA it is showing
                    complely non-magnetic state. I also checked for U=2
                    eV, but still GGA gave a magnetic solution but LDA
                    remains non-magnetic. I have also used a very fine
                    k-mesh (16x16x12) but still LDA remains
                    non-magnetic. I also checked it with PAW
                    pseudopotential method as implemented in VASP, for
                    both GGA and LDA, and results were consistent with
                    the full potential GGA. Why full potential LDA is
                    not showing the magnetic state??. I have properly
                    checked the inorb and indmc files and the parameters
                    are fine.</div>
