| 中文摘要 | The symmetry of the 3d9L* states induced by doping has been studied in a superconducting La2-xSrxCuO4 (x = 0.08, T(c) = 20 K) single crystal by polarized Cu L3-edge X-ray absorption spectroscopy (XAS) by using synchroton radiation. The integral of the unpolarized white line at threshold increases by 15% going from the insulating La2CuO4 to the superconductor La1.92Sr0.08CuO4 due to the additional 3d9L* states formed in the gap. The weight of the 3dx2-y2(9)L* (3d3z2-y2(9)L*) states is obtained from the variation of the polarized E perpendicular-to c and E parallel-to c spectra is found to be 70% (30%) of the total 3d9L* states. These experimental results show that the orbital angular momentum of the 3d holes is not frozen in the m(l) = 2 (3dx2-y2) symmetry in the doped cuprate perovskite suggesting the presence of a second band with mostly 3d3z2-r2 character close to the Fermi level. |
