Mixed valence states in lead perovskites

Scientists at Tokyo Institute of Technology, the Kanagawa Academy of Science and Technology have reported an unusual charge distribution of Pb2+Pb4+3Co2+2Co3+2O12 for a perovskite PbCoO3 synthesized at 12 GPa, with charge ...

CMR induced in pure lanthanum manganite

Colossal magnetoresistance is a property with practical applications in a wide array of electronic tools including magnetic sensors and magnetic RAM. New research from a team including Carnegie's Maria Baldini, Ho-Kwang "Dave" ...

A new and game-changing magnetoresistance

More than 150 years ago, William Thomson, later Lord Kelvin, discovered the magnetoresistive effect. Today, this finding enables sensors to measure the rotational speed of a car wheel, and is also used in compass navigation ...

Observing electrons in real-time could lead to faster computing

(Phys.org) —New research revealing the interactions between electrons and organic carrier materials in devices that use electron spin to encode information could help in the development of faster and more efficient data ...
