Discovery of new colossal magnetoresistance mechanism

A NIMS research group has discovered a new material, NaCr2O4, which displays a novel type of colossal magnetoresistance effect. The new material was developed by ultra-high pressure synthesis.

An electronic bucket brigade could boost solar cell voltages

If solar cells could generate higher voltages when sunlight falls on them, they'd produce more electrical power more efficiently. For over half a century scientists have known that ferroelectrics, materials whose atomic structure ...

Enhancing the magnetism

(PhysOrg.com) -- Berkeley researchers find enhanced and controllable magnetization in unique bismuth ferrite films.

Japan develops vehicle motor free of rare earths

Japanese researchers said Thursday they had developed a hybrid vehicle motor that is free of rare earths, the minerals that are now almost exclusively produced by China.

New Path To Solar Energy Via Solid-State Photovoltaics

(PhysOrg.com) -- Berkeley Lab researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new path to energy production brightens the future for photovoltaic technology ...

Researchers take the lead out of piezoelectrics

There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect. A lead-free alternative to the current crop of piezoelectric ...

Electric Switches Hold Promise for Data Storage

(PhysOrg.com) -- Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist. They are potential cornerstones in future magnetic data storage and spintronic devices ...
