The dielectric permittivity as a function of frequency may show resonance behavior in the case of gas molecules as studied in microwave spectroscopy (25) or more likely relaxation phenomena in soUds associated with the dissipative processes of polarization of molecules, be they nonpolar, dipolar, etc. There are exceptional circumstances of ferromagnetic resonance, electron magnetic resonance, or nmr. In most microwave treatments, the power dissipation or absorption process is described phenomenologically by equation 5, whatever the detailed molecular processes. 

Magnetic resonance in an assembly of ferromagnetic nanoparticles in ferrofluids, glasses and other systems has attracted much attention. But, up to now, only a few attempts have been made of quantitative, computer-simulation based analysis of SPR spectra of magnetic nanoparticles dispersed in glassy systems [2-11].

The cobalt catalyst prior to catalysis experiments have been shown to be less than 10 A in size by several methods including chemisorption methods, ferromagnetic resonance and spin echo nuclear magnetic resonance techniques (11, 20, 27). The transmission... 

Magnets are essential to most magnetic resonance experiments. (The exceptions include NQR and zero field NMR such as in ferromagnetic samples but an auxiliary field is quite often desirable even then.) There are four kinds of magnets to consider for use in magnetic resonance air-core... 

The diffusion coefficient can also be determined from measurements of other phenomena that are controlled by the activated motion of atoms. These indirect methods include internal friction measurements, nuclear magnetic resonance spectra, and some magnetic relaxation phenomena (in ferromagnetic substances). These techniques are advantageous in allowing the measurement of D at lower temperatures than are practicable by the conventional methods. 

The technique using non-magnetic metallic single crystals in NMR was long ago introduced by Jones and Williams (1962), when they analysed the anisotropy of the nuclear magnetic resonance in white tin. It is only 14 years ago, however, since the techniques appropriate for the NMR of ferromagnetically ordered metallic single crystals were introduced by Fekete et al. (1975). However, the requirements for the sample preparation are relatively severe. Otherwise the full...
