Inverse Photoemission Spectroscopy

ABSTRACTSpin- (and angle-) resolved inverse photoemission spectroscopy (SPIPES) has beenused for studying magnetic thin films. The spin dependence of the unoccupiedelectronic structure has been investigated for in-situ-grown epitaxial, ultrathin Fe and Cofilms on W(001). The Fe overlayers have a square lattice and exhibit in-plane magneticremanence in the direction of the surface Brilluoin zone. Four or more atomic layersof Fe show bulklike SPIPES spectra with a majority spin peak at the Fermi energy (EF)and a broad minority peak 1.3 eV above EF The Co overlayers on W(001) showdistorted hexagonal structures in the plane with an atomic density twice that of theW(001) plane. Two atomic layers of Co show strong in-plane magnetic remanence withthe minority peak at 0.7 eV. The SPIPES results in general are consistent with thetheoretical electronic structure for momentum-conserving radiative transition from freeelectron-like bands down to the unoccupied 3d bands.

A Performance

For a spin-resolved inverse photoemission spectrometer, the most important component is the electron optics system consisting of a 90° deflector and lenses to transfer the spin-polarized electrons from a GaAs photocathode to the sample at high transmission. We adopt a cylindrical deflector when we construct a spin-resolved inverse photoemission spectrometer. A performance test shows that our electronic optics system has achieved 83% transmission, and also that the cylindrical deflector has no shortcoming compared to the spherical type.
