Effect of mechanical stress on loss, permeability and magnetostriction
Mechanical stress can causes magnetoelastic energy to be stored in a magnetic material. When this happens the magnetic domain structure changes to minimise the total energy. This, in turn, affects all the structure sensitive magnetic properties such as losses, permeability and magnetostriction. This chapter opens with an explanation of the effect of stress on simple domain structures in iron or SiFe single crystals. This knowledge can be used to understand the practical stress sensitivity characteristics of real materials discussed in Chapters 5, 6, and 8 of Volume 2 of this book.
