| Abstract: | The mixed Zn0.75Ni0.25Fe2O4 ferrite was studied by the neutronographic method within the temperature region of 1.8–77 K. It is shown that besides the usual ferrimagnetic order at 1.8 K there exist superstructure reflections. The experimental results are treated in the framework of the helicoidal magnetic structure. The transition temperatures and some other parameters of the magnetic structure are given. The results of calculation are in good agreement with the experimental data. |
