Description
Summary:Magnetic microwires are unique materials with a wide range of magnetic and high-frequency properties that are of considerable interest from the point of view of the application for magnetic sensors based on microwires. The magnetic properties of microwires directly depend on the level and distribution of stresses. Therefore, the study of the magnetic properties of microwires, depending on their stressed state, is of considerable interest. This paper describes a method for measuring the hysteresis properties of amorphous microwires under stretching in situ. An experimental facility has been developed. It allows measuring the dependences of the coercivity of microwires under stretching in situ with an error of no more than 8 A/m with an external magnetizing field of 2000 A/m and a frequency of 2.5 kHz.
