- Title
Piezomagnetism and stress-induced paramagnetic Meissner effect in mechanically loaded high-T[sub c] granular superconductors.
- Authors
Sergeenkov, S. A.
- Abstract
Two novel phenomena in a weakly coupled granular superconductor under an applied stress are predicted on the basis of a recently suggested piezophase effect (a macroscopic quantum analog of the piezoelectric effect). Namely, the existence of a stress-induced paramagnetic moment in zero applied magnetic field (piezomagnetism) is considered, and its influence on the low-field magnetization (leading to a mechanically induced paramagnetic Meissner effect) is investigated. The conditions under which these effects can be experimentally measured in high-T[sub c] granular superconductors are discussed. © 1999 American Institute of Physics.
