Applying pressure reaps material rewards

Researchers in Japan have succeeded in growing single crystals of yttrium manganite (YMnO3) using a high-pressure material-growth technique1. Developed by Shintaro Ishiwata and his colleagues from the RIKEN Advanced Science ...

Long-time mystery in cobalt oxides

The existence of an intermediate-spin (IS) state in cobalt oxides has long been a subject of dispute. A recent resonant X-ray scattering experiment has clearly demonstrated Co3+ eg orbital ordering in Sr3YCo4O10.5, which ...

Structural origin of 'hidden state' in manganite thin film revealed by picosecond time-resolved X-ray diffraction

Photo-induced phase transition (PIPT) has caused great excitement in materials science because ultra-fast alteration of the magnetic, dielectric, structural and optical properties of materials can be brought about with very ...

Multiferroics could lead to low-power devices

(Âé¶¹ÒùÔºOrg.com) -- Magnetic materials in which the north and south poles can be reversed with an electric field may be ideal candidates for low-power electronic devices, such as those used for ultra-high data storage. But finding ...

Domain walls that conduct electricity

The logic and memory functions of future electronic devices could shrink dramatically - to one or two nanometers (billionths of a meter) instead of the many tens of nanometers that characterize today's most advanced elements ...
