It has been well known that the stability of the superconducting state against thermal fluctuation can be manipulated by applying static strain such as that produced by either stretching or squashing. We have succeeded in manipulating the Meissner signal of a typical cuprate superconductor Bi2Sr2Ca2Cu3Ox (termed Bi2223) with a dynamical stress of 1 MHz frequency, generated by a piezoelectric device. The magnitude of the superconducting transition temperature (Tc) shift observed there exceeds one hundred times as much as those under static strain. We consider that the acoustic stress induces dynamic perturbation toward the lattice, resulting in the suppression of the formation of Cooper pairing.
