en original Matrix material structure dependence of the embedded electron spin decoherence
In this article we present the novel application of nuclear spin bath model and cluster correlation expansion method on studying matrix material structure via embedded electron spin decoherence. Profiles of embedded electron spin decoherence under Carr-Purcell-Meiboom-Gill dynamical decoupling pulse series in a model system for organic solids (malonic acid) are calculated for various different structures. Resulting decay profiles exhibit strong correlation to the variations of adjacent proton environment among them. In addition, the decoherence behaviour of embedded spin in proton spin bath(s) of organic solids is found to be significantly different to bath models with other nuclei through the violation of the even-odd pulse parity, which characterizes the influence of large dipolar coupling between protons at quantum level. Theoretical predictions of decoherence profiles in polycrystalline, relative distribution of Hahn echo signal decay time scales among single crystal orientations and the reduction of Hahn echo signal decay time scale by disorder are positively verified by experiments.
