Introduction The existing methods for measuring magnetostriction are contact and are based on the creation of strong magnetic fields, the use of fiber optics, or strain gauges (Samata et. al., 2000). The formation of strong magnetic fields is almost always associated with the release of a large amount of heat, which can cause temperature drift during measurements, and imposes special requirements on the design of the measurement setup. Optical methods can be an example of non-contact measurement of magnetostriction characteristics. In this paper, we consider the application of the laser interferometry method for measuring the magnetostriction of bulk Abstract The possibility of non-contact measurement of the magnetostriction of bulk ferromagnets using laser interferometry is shown.
