MICROFABRICATION IN THE STUDY OF GIANT MAGNETORESISTANCE - RECENT RESULTS

Microstructuring can give access to new experimental geometries for st udying the giant magnetoresistance in magnetic multilayers, such as th e one in which the current is perpendicular to the plane of the multil ayer (the so-called CPP-geometry), We discuss several experimental met hods that give access to this geometry and discuss in more detail a me thod in which a multilayer is evaporated at an angle onto nano-grooved substrates. Using the latter technique, we have determined the spin-d ependent bulk and interface scattering parameters in Co/Cu multilayers as a function of the temperature.
