20100013469 | Method and Device for Simultaneous Measurement of Magnetostriction and Magnetization - Since a measurement of a magnetostriction is accompanied by a measurement of a magnetization of a sample to be measured, the magnetostriction and the magnetization are measured by separately prepared devices, with efforts for observing the coextensive volumes of the sample. Measurements of the magnetostriction and the magnetization are difficult due to the difficulty of correction and calibration. The value of macroscopic external mode magnetostrictive coefficient cannot be correctly determined at low temperature regions. A convenient method which enables the measurement of the magnetostriction and the magnetization simultaneously at the coextensive volumes of the sample, is developed by combining the method of the measurement of the magnetostriction by an X-ray diffraction method an the method of the X-ray magnetic diffraction method. This method comprises the steps of measuring the relative diffraction intensity change (δ) at ascending magnetic field and the descending magnetic field respectively in the magnetic field at the coextensive volumes of the sample, obtaining asymmetry component δ | 01-21-2010 |
