Many aspects of this nonlinear dynamics still remain unclear, and not all of them can be explained in the simple framework of the Bloch equations, which calls for a more complete description of the spin system. In particular, in this context, the large magnetization of such highly polarized samples that entails the presence of large distant dipolar fields, contributes to the dynamics of the magnetization. This is unusual in solid state NMR, where dipolar interactions between nuclear spins are of paramount importance, but have no other effect on the magnetization dynamics other than a fast decoherence, therefore a large line broadening with line widths of tens of kHz. In contrast, possible effects of distant, much weaker, dipolar interactions, requires the persistence of coherent magnetization on a much longer time scale. The effects of the associated distant dipolar field (DDF) has been studied in the particular context of solid 3 He in a seminal paper by Deville et al.. In that work, the unusual long transverse relaxation time allowed to observe such effects. These were subsequently investigated mainly in solution NMR, where the combination of radiation feedback and the distant dipolar field have been the subject of a number of studies. Thus, the combination of both these effects have been shown to produce complex magnetization dynamics, such as spin turbulence and spectral clustering. In typical solid state NMR samples, short NMR decoherence times prevent the development of dynamical effects of the distant dipolar field (DDF), and to our knowledge, no study of the combined collective effects of radiation feedback and the distant dipolar field have been investigated in this context. Here, we explore the dynamics of a magnetization subject to these combined effects in the context of DNP-hyperpolarized spins at liquid helium temperatures, both numerically and experimentally. We provide evidence for the manifestation of the DDF at long evolution times of the magnetization and show that the fine features of the observed maser pulses can be related to the interplay between the latter and radiation feedback.
