摘要：
Paper presents the results of investigation carried out on the magnetostrictive and magnetoelastic characteristics of high-permeability Mn0.51Zn0.44Fe2.05O4 ferrite. During the investigatation of magnetostrictive characteristics of the ferrite, the semiconductor strain gauges mounted on the frame-shaped samples were utilized. The same frame-shaped samples were used for investigation of magnetoelastic characteristics Of Mn0.51Zr0.44Fe2.05O4 ferrite. Presented results confirmed that high-permeability Mn0.51Zn0.44Fe2.05O4 ferrite has near-zero, negative magnetostriction. Moreover, in spite of its low magnetostriction, this ferrite is highly sensitive on steresses from external forces.
