Acoustic nuclear magnetic resonance ANMR

As indicated above, for solids it is possible to transfer energy between nuclear spins and the lattice via phonons generated within the sample. Kastler [4] and Altershulter [5-7] proposed that it should also be possible to utilize this path in reverse, with applied phonons (ultrasound) causing a nuclear spin system to experience a net absorption of energy, and result in detectable acoustic nuclear magnetic resonance (ANMR) spectra.
