| 中文摘要 | 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 co(2+) in la(2)comno(6) and hence modifies electronic structure of la(2)comno(6). we find a metal-insulator transition in la(2)comno(6), which originates from the interplay between the strain induced lattice distortion and electron correlations. such transition is understood upon the orbital polarization of co(2+), which takes on the d(xz/yz) character under compression, yet switches to the d(x2-y2) character under tension. the orbital switching presented should hold promise for many technological applications.
