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 weak photonic excitation as a result of cooperative interactions. An essential question that arises is how we can identify a novel phase of solid that is uniquely generated under photo-excited conditions.

A custom-built, $2.5 million "split magnet" system with the potential to revolutionize scientific research in a variety of fields has made its debut at the National High Magnetic Field Laboratory at Florida State University.

While insulating against electrical currents

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.

On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field – for a period of a few milliseconds

(PhysOrg.com) -- Electrons behave like football teams: the match becomes interesting when the teamwork is as good as that conjured up by the players of FC Barcelona. Electrons which interact strongly with each other give rise to superconductivity, the lossless transport of current, for example

(PhysOrg.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.

Using well-known patterned media, a team of researchers in France has figured out a way to double the areal density of information by essentially cutting the magnetic media into small pieces and building a "3D tower" out of it.

(PhysOrg.com) -- Magnetic vortex cores, which can be used as particularly stable storage points for data bits, can now be switched much faster.

With the sweet scents from the adjacent sake brewery wafting through the air, Elizabeth Norris is busy selling, framing, and restoring intoxicating treats of a different kind. Covering the magnetic walls of her Vintage European Posters shop in Berkeley, Calif., are massive movie posters displaying vivid colors, conveying lots of ...

(PhysOrg.com) -- University of Utah researchers built "spintronic" transistors and used them to align the magnetic "spins" of electrons for a record period of time in silicon chips at room temperature. The study is a step toward computers, phones and other spintronic devices that are faster and use less energy than their electronic counterparts.

In the hard drive industry, the rapid growth of storage density has been propelled in part by developments in the sensors used to read the magnetic "bits" on the disk. Recently, the use of giant magnetoresistance (GMR) in such sensors, with current flowing in the plane of a multilayer film, has given way to the use of tunneling magnetoresistance, where current flows perpendicular to the plane of the multilayer through a tunnel barrier.

Rare earths are an expensive and necessary component of strong permanent magnets.
