Systematic pressure enhancement of titanomagnetite …
A study on the reversible susceptibility of multidomain titanomagnetite showed that initial susceptibility and saturation moment decrease as a function of increasing pressure and titanium concentration [ Gilder and Le Goff, 2005 ]. The influence of stress on the piezo-remanent magnetization of the titanomagnetite series remains poorly known.

Effects of titanomagnetite reordering processes on …
We have modeled the effects of T c variations in titanomagnetite arising from a thermally activated reordering process on standard thermal demagnetization and paleointensity experiments. The results have important implications for the interpretation of many paleomagnetic studies which rely on a titanomagnetite-bearing remanence.

Titanomagnetite – Silicate Melt Oxybarometry
The oxidation state of magmas is a parameter of prime importance in magmatic processes. Although various techniques exist to reconstruct the oxidation state of magmas, this task remains challenging, particularly in the case of intrusive rocks. Titanomagnetite is a ubiquitous phase in most magmatic rocks and due to its ability to …
