Long-term memory and magnetoacoustic responses at excitation of magnetostrictive materials by RF pulses using pulsed NMR technique

Different long-term acoustic memory and magnetoacoustic effects were observed in magnetostrictive materials at their inductive excitation by radiofrequency (RF) pulses using pulsed NMR techniques. Along it the stimulated domain-acoustic echo, possessing a long-term acoustic memory was inductively excited by three RF pulses in magnetite and magnetoelectric ferrite-piezoelectric layered composites using pulsed NMR technique with inductive and electric recording of DAE signals.
