Note: $I_{n}$ – natural remanent magnetization; $\chi$ – magnetic susceptibility; $Q$ – Koenigsberger ratio; $I_{s}$ – saturation magnetization; $I_{rs}$ – remanent saturation magnetization; $H_{c}$ – coercive force; $H_{rc}$ – remanent coercive force; $T_{c}$ – Curie temperature for magnetite; $I_{st}/I_{so}$ – ratio of the saturation magnetization of the sample after its heating to 700° C to its initial saturation magnetization; $C$ – volumetric percentage of magnetite in the sample calculated from the saturation magnetization value $I_{s}$. |
