Role of incoherent phonons in resonant interaction of ultrasound with a nuclear spin system
Golenishchev-Kutuzov V.A., Sadykov I.I., Khaimovich E.P.
Direct acoustic magnetic resonance and acoustic saturation of NMR are investigated in InSb and Csl. Anisotropy of acoustic saturation of NMR is observed for the first time ever. The feasibility of correctly determining the spin-phonon coupling constants and the incoherent-phonon lifetime is demonstrated.
