The electronic nematic state without magnetization emerges in variousstrongly correlated metals such as Fe-based and cuprate superconductors. Tounderstand this universal phenomenon, we focus on the nematic state inTi-oxypnictide BaTi2(As,Sb)2O, which is expressed as the three-dimensional10-orbital Hubbard model. The antiferromagnetic fluctuations are caused by theFermi surface nesting. Interestingly, we find the spin-fluctuation-drivenorbital order due to the strong orbital-spin interference, which is describedby the Aslamazov-Larkin vertex correction (AL-VC). The predictedintra-unit-cell nematic orbital order is consistent with the recentexperimental reports on BaTi2(As,Sb)2O. Thus, the spin-fluctuation-drivenorbital order due to the AL-VC mechanism is expected to be universal in varioustwo- and three-dimensional multiorbital metals.
