| Izvleček: | Title screen In this paper, magnetic phase transitions of nickel–zinc ferrites (Ni₁₋ₓZnₓFe₂O₄) with a zinc content of 0≤xZn≤0.7 were studied using the thermomagnetometric method, which is a thermogravimetric analysis with a constant magnetic field applied. The studied ferrites were made from oxide powders using ceramic technology. The Curie point was determined from the derivative thermogravimetric curve in the region of magnetic phase transition. The Curie temperature calibration curve was obtained against the degree of doping of nickel ferrite with zinc to detect the magnetic phases by the Curie temperature. Thermal analysis of multicomponent magnetic mixtures that consist of nickel–zinc ferrites with different zinc contents was performed. The dependence of the change in mass during magnetic phase transition on the mass content of the magnetic phase in the ferrite mixture was revealed.
