Query: Mechanically Stimulated Domain Re-arrangement in Cryogenic Magnetic
  Shielding Materials   Room temperature properties and behavior of several types of cryogenic
magnetic shielding materials are measured and reported here. Large changes in
the effective relative permeability are observed when the materials are
perturbed with a relatively small mechanical stimulation. The change in
permeability is a reversible effect.
