Transition metal oxides show rich physical properties which are often influenced by external perturbation. Here, we report by first-principles calculations that strain enables switching of orbital occupancy of Co2+ in La2CoMnO6 and hence modifies electronic structure of La2CoMnO6. We find a metal-insulator transition in La2CoMnO6, which originates from the interplay between the strain induced lattice distortion and electron correlations. Such transition is understood upon the orbital polarization of Co2+, which takes on the dxz/yz character under compression, yet switches to the dx2-y2 character under tension. The orbital switching presented should hold promise for many technological applications.
