Hemoilmenite
Ilmenite with intergrowths of hematite.
This material shows self-reversal thermoremanent magnetization. Cooling below Curie point, hemoilmenite is magnetized reversal to the external magnetic field, and acquires it as natural remanent magnetization.
Year of discovery: 1951 (Japan)
Locality list: 8 localities of hemoilmenite
