ANGLE-RESOLVED PHOTOEMISSION EVIDENCE FOR A GD(0001) SURFACE-STATE

[摘要] From angle resolved photoemission we have observed a surface state on Gd(0001) near the Fermi energy in the vicinity of GAMMA-BAR in agreement with a recently calculated band structure. This surface state is of prominent 5d3x2-r2 character (DELTA-1) at GAMMA-BAR. The observation of this surface state can be correlated with the development of the gadolinium bulk band structure which occurs with increasing film thickness as gadolinium films are grown on W(110).
