CRYSTAL CLEAR MEMORY
Ferroelectric crystals can remember sounds. So say researchers who
sent acoustical waves through a lithium niobate sample and saw the
tone reappear a moment later. The team, publishing in the 9
September print issue of PHYSICAL REVIEW FOCUS, thinks the effect could
serve as a non-destructive probe of the material, which is commonly used
in
telecommunications devices.
