Estimation of thermomagnetometry method sensitivity for magnetic phase determination

Abstract

In this article, the sensitivity of thermomagnetometry method for magnetic phase determination in lithium substituted ferrites was estimated by thermogravimetric analysis in magnetic field of lithium-zinc ferrite and iron dioxide (Li_0.4Fe_2.4Zn_0.2O₄+α-Fe₂O₃) components mixture with different mass proportions: 2, 4, 6, and 100 mass% Li_0.4Fe_2.4Zn_0.2O₄ phase in total mixture. Thereby, analyzed samples are mixture of magnetic and nonmagnetic phases. Results of thermomagnetometric analysis were supplemented with the X-Ray diffraction analysis data. It was shown that the thermomagnetometry method allows to determine a magnetic phases with mass content not less than 2 mass% in analyzed mixture. In this case, we can clearly estimate the position and intensity of the peak on derivative thermogravimetric curve, which connected with a magnetic phase transition in ferrite at Curie temperature.
