Relaxation and relaxation-diffusion correlation measurements have emerged as essential tools for magnetic resonance of materials. Examples of correlation measurements include the T1-T2, the T2-D, and the T1-T2∗ variants. In this paper, we describe the implementation and validation of a T2-T2∗ relaxation correlation measurement. It is shown that this technique effectively distinguishes microscopic environments dominated by local field inhomogeneity from those dominated by nuclear spin-spin interactions. The method is demonstrated in simulation and in glass bead packs.

In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers...
