There are two distinct peaks in the ranges of 4–6 and 9–11 GHz. That at 4–6 GHz may be the Kittel natural resonance of magnetite itself, while that at 9–11 GHz may be the exchange coupling resonance between the magnetite and the aggregate matrix [26]. The magnetic loss tangent of the MHAs also increases with the iron oxide content, and ...

Magnetite, a common microwave-absorbing material, is an outstanding microwave absorber that can be used in pavements for deicing. In this work, magnetite was scattered in functional aggregate as a microwave-deicing functional phase, and the microwave-heating aggregate (MHA) was prepared by means of sintering to realize aggregate functionalization.
Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).
