The coupling between ferromagnetic (FM) layers separated by a non-ferromagentic
or an antiferromagnetic (AFM) spacer has attracted a lot of interest over the
past few years. These systems provide new standards for magnetic materials and
devices used in magnetic data storage, magnetic sensors and biomedical
industries.
To develop the technological potential of
magnetic nanostructures it is important to understand how the electron spins
behave at the interfaces and how to design new materials. To do this we
have synthesized different magnetic multilayers and measured their spin
properties through spin-polarized low-energy electron microscopy.
