TOWARD A THEORY OF NUCLEAR MAGNETIC RESONANCE IN FERROMAGNETICS WITH LOW MAGNETIC-NUCLEUS CONCENTRATIONS, I.
Abstract
The nuclear magnetic resonance in ferromagnetic materials containing small concentrations of magnetic nuclei is treated in terms of the Hamiltonian for a specific electronic spin system. It is found that the use of this Hamiltonian yields correlation functions which pertain only to the electronic spin system. The latter functions are used to derive expressions for the magnetic material and the intensity, line width, and frequency shift of the resonance line. It is noted that, in the general case, the imaginary part of the magnetic susceptibility will be given by the sum of the dispersion and absorption curves and that the mass operators M(bb) and P(k), which affect the nuclear magnetic resonance, arise not as the direct result of spin wave extinction (since the former appear not with their eigen-frequency) but rather with the frequency of NMR.
