The following paper presents original results of study on the magnetoelastic properties of Ni-Zn (nickel-zinc) ferrite material under low magnetizing fields, corresponding to the so-called Rayleigh region. The investigated Ni_{0.36}Zn_{0.64}Fe₂O₄ material was formed into frame-shape sample allowing to obtain uniform stress distribution. Special digitally controlled measurement system was utilized to perform investigation. Obtained results are presented in the paper. On the basis of them mathematical description of magnetoelastic effect in investigated material was developed as an extend of the Rayleigh model of magnetic hysteresis. Comparison of the experimental and modeling results indicates that the developed model is correct.
