s. We have studied phonon hole burning phenomenon. According to the plastic deformation model proposed by us, some characteristics of holes depend on the amplitude of resonant oscillation exited and the crystal condition of specimen. We studied the effect of heat treatment for the particles on holes. In NH4HZP04 specimen, the increase of decay time for(More)
The notion of the spectral hole burning phenomena was applied to the piezoelectric resonators. The oscillation characteristics of particles, whose resonant frequencies are coincide with that of the applied electric field, were modified and the traces of pulse shape were left in their absorption spectrum as the hole burning. The plastic deformation was(More)
The writing of indentations in piezoelectric resonators was achieved by applying large amplitude oscillation, which introduced plastic deformations. The reading out of indentations was attained in the resonant oscillation space. They were described with the same notion as the hole burning phenomena. The detected indentation figures were well described the(More)
