Controlling self-doping in magnetite with temperature

One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks ...

Ultra-thin film of magnetite optimized for spintronics

From practical applications such as secure communications to complex scientific questions such as how the brain works, classical computing isn't always up to the task. Now, researchers from Japan have a made a discovery that ...

Magnetite nanowires with sharp insulating transition

Magnetite (Fe3O4) is best known as a magnetic iron ore, and is the source of lodestone. It also has potential as a high-temperature resistor in electronics. In new research led by Osaka University, published in Nano Letters, ...

Lipid vesicles transmit luminous or electrical signals

Liposomes are small spherical vesicles with walls comprising two layers of lipids and containing an aqueous core. These artificial structures have been developed for drug delivery or as carriers of active substances in cosmetic ...
