Zusammenfassung:Apparatus for measurements of internal friction from Q − 1 ∼ 1 0 − 6 and elastic moduli in the kilohertz frequency range in which external friction losses were minimized using a new-type of three-reed tuning fork as a sample under study is described. High sensitivity of the apparatus made it possible to observe a resonance plasticization of diamagnetic LiF crystals under the action of crossed magnetic fields ( ≈ 100   μ T ) in the EPR conditions.
