Ferromagnetic surface

The instrumentation required to measure the hysteresis loop of a ferromagnetic surface with MOKE can be very simple. Figure 4a shows one such implementation of the experimental setup for analysis of ultrathin film samples maintained in a...

Fig. 2.8 Auger de-excitation process (for details see text) for a spin polarized metastable He beam interacting with a ferromagnetic surface (/eff > d>). Due to the spin selectivity of this process, differences in the spin resolved density of states in the outermost layer (schematically shown on the left hand side) lead to different intensities of ejected electrons with majority (I) or minority (J.) spin...

As discussed in Sect. 5.1.2 it turned out that magnetic dichroism experiments are able to determine magnetic properties. In the following it will be shown that this experimental technique also allows the investigation of the magnetic behavior of adsorbate atoms on ferromagnetic surfaces [93]. 

Table 5.2-18 gives the values of pb, Pn, and Apsb for various ferromagnetic surfaces.
