Patent ID: 8036338

Claim:
A method for simultaneous measurement of magnetostriction and magnetization of a sample at coextensive volumes of the sample, comprising the steps of: measuring a relative diffraction intensity change (δ) at an ascending magnetic field and at a descending magnetic field respectively in the coextensive volumes of the sample to obtain an asymmetry component (δ A ) and a symmetry component (δ S ) of a magnetic field (H) from the relative diffraction intensity change (δ) at the coextensive volumes of the sample; obtaining a magnetostrictive coefficient (λ 100 ) at the coextensive volumes of the sample based on the symmetry component (δ S ); obtaining a relative magnetization (M/M s ) at the coextensive volumes of the sample based on a value (R′ a ) obtained by recomposing the asymmetry component (δ A ) and the symmetry component (δ S ); and displaying the magnetostriction and magnetization at the coextensive volumes of the sample.
