抄録

An essay for the formulation of magnetoelastic interactions is pressented in polycrystalline ferromagnetic materials. The special attention is directed to the stress-strain characteristics in polycrystalline materials known as the ΔE effect. The new variable, the relative volume of magnetic domains in a crystallite with multi-domain structure, is introduced to explain the ΔE effect in demagnetized specimen, which could not be understood by the earlier theory of magnetoelastic interactions. It is shown that the stress induced magnetostriction is arised, and that the apparent elastic stiffness is reduced independently of the sign of magnetostriction constant. Specific examples of uniaxial stresses, shear stresses are examined to show the occurrence of the ΔE effects also in polycrytalline materials.
