Abstract

The influence of the skin effect on single and triple (spin echo) gamma detected pulsed NMRON signals is calculated using a density matrix approach within a pure Zeeman manifold. For single pulse NMRON the turn angle dependences of the signals for uniform and exponential profiles of the resonant nuclei are presented for a typical inhomogeneous broadening applicable to intermediate mass impurities in ferromagnetic hosts. For triple pulse NMRON the baseline and principal spin echo amplitudes for equal resonant rf pulses are presented for the same inhomogeneous broadening. It is found that the skin effect leads to the form of pulsed NMRON signals that are in accord with experiment.
