Scattering spin-dependent

Measurements of the self-correlation function with neutrons are normally performed on protonated materials since incoherent scattering is particularly strong there. This is a consequence of the spin-dependent scattering lengths of hydrogen. Due to spin-flip scattering, which leads to a loss of polarization, this... 

Spin-dependent scattering, interlayer coupling, and tunnel magnetoresistance in trilayer structures... 

Figure 2. Asymmetric spin dependent scattering at CoFe/Cu and NiFe/Cu interfaces leads to the giant magnetoresistance effect observed in a (CoFe/Cu/NiFe/Cu)x2o multilayer stack (S. Cardoso, INESC MN).

The use of polarised beams in collision studies has enabled experimentalists to perform very detailed tests of theoretical models, particularly with regard to the role of electron exchange and the spin—orbit interaction in spin-dependent scattering. We will now briefly discuss the role of these interactions before using the general density matrix method to describe the more general case where more than one mechanism may contribute to the spin-dependent effects.
