Magnetostrictive Coefficient Measurement Analytical Service

The measurement of the magnetostrictive coefficient involves quantifying the extent to which a material changes its shape or dimensions when subjected to a magnetic field. Magnetostrictive materials, such as certain metals and alloys, exhibit this property due to the reorientation of magnetic domains within the material. This phenomenon is essential in various applications, including sensors, actuators, and transducers, as it allows for the conversion of magnetic energy into mechanical motion and vice versa. Measurement techniques typically include strain gauge methods, laser interferometry, or capacitance-based displacement measurement for accurate determination。

Sample Requirement

Sample Condition: Currently, only bulk samples are measured; flexible thin films are not tested (rigid thin sheets can be tested).

Optimal Size Requirements:

• For tests without applied pressure, the surface in the direction of sample expansion should be as large as possible, with at least one edge >10 mm and the other edge >6 mm.
• For tests with applied pressure, the sample must be cylindrical. The diameter or side length should be 10–45 mm, and the height should be 40–55 mm. The parallelism of the two end faces should be as high as possible, with a deviation of less than 0.05 (the flatter, the better). It is recommended to polish the testing surface with sandpaper beforehand.
