A NEW-TYPE OF MAGNETIC LINEAR DICHROISM AT FE AND CO M(2,3) EDGES

We have found a new type of magnetic linear dichroism in photoyield sp ectra at the Fe and Co M(2,3) edges. Spectra excited by p-polarized li ght at oblique incidence show cross section dependence on the sign of the magnetization. The experimental geometry is the same as that of th e transverse magneto-optic Kerr effect (T-MOKE). The dichroism is enha nced when the light impinges on the sample towards grazing incidence. The T-MOKE at the Co M edge also measured simultaneously. The new type of dichroism can be applied for imaging of magnetic domains of surfac es by a photoelectron microscopy.
