Fu. Hillebrecht et al., NEW MAGNETIC LINEAR DICHROISM IN TOTAL PHOTOELECTRON YIELD FOR MAGNETIC DOMAIN IMAGING, Physical review letters, 75(11), 1995, pp. 2224-2227
We report a dependence of the photoabsorption cross section as measure
d by total electron yield at the Fe and Co 3p thresholds on the sign o
f the magnetization for p-polarized light at oblique incidence. Peak-t
o-peak asymmetries up to 4% are observed. The asymmetry increases towa
rds grazing incidence, where the total sample current is smallest. The
transverse magneto-optic Kerr effect measured simultaneously shows a
peak-to-peak asymmetry of up to 23% at the Co 3p threshold. The dichro
ism is used to image magnetic domains on an Fe(100) surface in a photo
electron emission microscope.
