The results of studying the changes in the domain structure of a planar square microparticle with size 7.5 x 7.5 x 0.04 μm under uniaxial mechanical stress is presented. Microparticles were made from the following materials: permalloy (18% Fe, 82% Ni), permendur (50% Co, 50% Fe), halfenol (16% Ga, 84% Fe), Ni, terfenol (Tb0.3Dy0.7Fe1.92). The conclusions about the promising of using these materials for fabrication microsensors for stress detection and for fabrication straintronic devices for processing and storing information were made. Keywords: magnetoelastic effect, magnetic force microscopy, planar ferromagnetic particles, domain structure.
