A synthetic compound long known to exhibit interesting transition properties may hold the key to new, non-magnetic forms of information storage, say researchers at the RIKEN SPring-8 Center and their collaborators. The team's latest findings shed light on the complex relationship between a compound's electron spin arrangement and its transport properties, an area researchers have long struggled to understand.

Researchers at the RIKEN Advanced Science Institute (Japan) have developed a unique way to create full-color holograms with the aid of surface plasmons.

A variety of imaging technologies rely on light with short wavelengths because it allows very small structures to be resolved. However, light sources which produce short, extreme ultraviolet or x-ray wavelengths often have unstable emission wavelength and timing.

Molecules and polymers have unique electronic and optical properties suitable for use in electronic devices. These properties, however, are complex and not well understood

Water (H2O) has a simple composition, but its dizzyingly interconnected hydrogen-bonded networks make structural characterizations challenging. In particular, the organization of water surfaces—a region critical to processes in cell biology and atmospheric chemistry—has caused profound disagreements among scientists

Storing information in long-lasting quantum states is a prerequisite for building quantum computers. Intrinsic properties of nuclei known as magnetic spins are good storage candidates because they interact weakly with their environment; however, controlling them is difficult

Building electronic devices that work without needing to actually transport electrons is a goal of spintronics researchers, since this could lead to: reduced power consumption, lower levels of signal noise,

Institute for Solid State Physics, the University of Tokyo and RIKEN announced that researchers from both institutes succeeded in the magnetic control of anomalous Hall effect (AHE) induced by spin chirality.

At the Radioactive Isotope Beam Facility (RIBF) of the RIKEN Nishina Center for Accelerator Science in Wako, a research team has measured the time it takes for 38 extremely rare isotopes to decay by half. This is the first study of half-lives for 18 of the isotopes. The data provide a long-awaited test of theoretical predictions of the rate at which these isotopes decay, and will help nuclear physicists to understand a fundamental source of many of the atomic elements and their isotopes

(PhysOrg.com) -- Spintronics — also known as magnetoelectronics — may replace electronics as the medium of choice for computer memory. The discovery of a mechanism that produces permanent magnets at room temperature, without any external influence, may soon improve the design of spintronic devices. Takumi Ohtsuki from the RIKEN SPring-8 Center, Harima and his colleagues in Japan, made the discovery in a class of material called a dilute ferromagnetic oxide.

The ubiquitous and unremarkable magnet, BaFe12O19, is manufactured in large volumes, has the simplest crystal structure in its class, and is often seen on refrigerator doors—but it is set for an interesting future. By substituting a few of its iron atoms with the elements scandium and magnesium, Yusuke Tokunaga and Yoshinori Tokura from the Japan Science and Technology Agency, along with Yasujiro Taguchi from the RIKEN Advanced Science Institute and their colleagues, have produced a very rare magnet. The rarity of the magnet lies in three features that, taken together, endow it with a high degree of tunability.
