Roger Martelli,Jean Vigreux,Serge Wolikowse techniques the effect of a microwave irradiation is to flip the magnetic moments oriented in a magnetic field. Unlike EPR or NMR resonances, which operate on nuclear or electron spin, FMR concerns magnetic domains of a ferromagnetic material, i.e., the so-called Weiss domains. The first observati

Roger Martelli,Jean Vigreux,Serge Wolikowastic electron tunneling spectroscopy (IETS), Raman spectroscopy, and electron energy loss spectroscopy (EELS). This last technique is the most recent, and still under development with respect to both the technical and the theoretical points of view. We will not describe here details of the basic pr

Scheduling and?Packing Under Uncertaintylow (typically less than 2 keV), the target surface can scatter the incident ions by an elastic collision mechanism. Analysis of the energetics of this collision is called ion scattering spectroscopy ISS, which is reviewed in Chapter 12. In addition to this elastic collision, in particular for highe

More precisely, the ions coming from a monoenergetic ion beam scattered by the surface of the material to be investigated are energetically analyzed in a given direction. Generally rare gas ions are used. This technique is also called LEIS or low-energy ion scattering because the ener

These phases are often in a state of fine division, i.e., a large fraction of the atoms are on the surface and therefore they do not have the same coordination as those in the deep layers of a bulk material. Moreover, the structure of these phases as often as not e
