Magnetic clusters in ilmenite-hematite solid solutions

Direct evidence of Fe/Fe charge order in the ferrimagnetic hematite- ilmenite Fe1.5Ti0.5O3-δ solid solution

A strong interplay between charge, lattice, orbital and spin degrees of freedom exists in transition-metal oxides yielding the emergence of a large spectrum of functionalities such as hightemperature superconductivity, metal/insulator transition, multiferroicity, thermoelectricity... More specifically, mixed valence states of 3d elements issue as a driving force in such interplay. In addition, ...

Magnetic Properties of Ilmenite‐Hematite Single Crystals from the Ecstall Pluton Near Prince Rupert, British Columbia

[1] Paleomagnetic studies of the 91 Ma Ecstall pluton and other Cretaceous plutons of British Columbia imply large northward tectonic movements (>2000 km) may have occurred during the tectonic evolution of western North America. However, more recent studies have shown that the eastern edge of the Ecstall pluton experienced considerable mineralogical changes as younger Eocene plutons, such as th...

Effects of nanoscale exsolution in hematite–ilmenite on the acquisition of stable natural remanent magnetization

To investigate the acquisition mechanism of high and stable natural remanent magnetization (NRM) in rocks of the Russell Belt, Adirondack Mountains, New York, we examined the exsolution microstructures and compositions of magnetic minerals using three samples with different magnetic properties. The samples contain titanohematite with ilmenite lamellae, end-member hematite without lamellae and r...
