Abstract
The magnetic field dependence of the longitudinal nuclear-spin relaxation time for $^{31}\mathrm{P}$ nuclei in paramagnetic GdP is shown to yield the Fourier transform of the sum of two electronic-spin correlation functions. This represents a new experimental technique for the study of paramagnetic spin dynamics. A reasonable fit to a theoretical spectrum is achieved, and the resulting exchange strength agrees with that deduced from the Curie-Weiss temperature.
