Abstract
Effect of uniaxial mechanical stresses on the initial susceptibility, saturation remanence, and coercive force of materials in which single-domain nanoparticles are carriers of magnetic properties has been studied theoretically. It has been shown that at small elastic stresses the above characteristics vary linearly; with increasing stresses, the growth of tensile stresses leads to a nonmonotonic variation of these characteristics, and the growth of compressive stresses, to a continuous decrease in the susceptibility and remanence and to an increase in the coercive force. With increasing plastic deformations, the position of the maximum in the stress dependence of the saturation remanence (or initial susceptibility) and the position of the minimum in the coercive force dependence are shifted to the region of greater values.
