An
international team of researchers has used SLAC’s Linac Coherent Light
Source (LCLS) to discover never-before-seen behavior by electrons in
complex materials known for their strongly correlated structures. The
unusual qualities of these materials, which include oxides such as
striped nickelate, stem from the collective behavior of their electrons.

The
performance of magnetic storage devices is limited by the way magnetic
domains interact when in close proximity. Researchers in the U.K. have
demonstrated that a honeycomb pattern of nano-sized magnets in a
material known as spin ice introduces competition between neighboring
magnets, and reduces the problems caused by these interactions by
two-thirds.

Until
the development of a new nanomaterial-based sensor in Germany, the
brain’s magnetic field was measurable only under technical laboratory
conditions. This prevented the technology’s use in medical applications.
The new sensors, however, operate at normal conditions. Neither cooling
nor external magnetic bias fields are required.

Thermal
stress can cause debonding between thin layers in microelectronics.
Taking advantage of the force generated by magnetic repulsion,
researchers have developed a new technique for measuring the adhesion
strength between thin films of materials used in these devices, and they
hope to apply the method improve solar cells or microelectromechanical
devices.

During
a six-experiment pulse this week, the previous world record for
laboratory-produced magnetic fields was broken by Los Alamos National
Laboratory researchers. The hundred-tesla field, about 2 million times
Earth’s magnetic field was produced with the help of a 1,200-MJ motor
generator.

Researchers
at Helmholtz Center in Germany have developed a magnetic valve that
could be an enabling technology for spintronics. The new structure
allows for data to remain stored even after electric current has been
cut, and memory in the valve can be re-written indefinitely.

Researchers
at the Max Planck Institute have put together a sandwich of a
ferroelectric layer between two ferromagnetic materials that responded
to a short electric pulse. This changes the magnetic transport
properties of the material in such a way that information can be placed
in four states instead of just two. The potential increase in storage
density is great.

Instead
of using a magnetic field to record information on a magnetic medium,
researchers in the U.K. recently harnessed much stronger internal forces
and recorded information using only heat. This new method allows the
recording of terabytes of information per second, hundreds of times
faster than present hard drive technology.

On
the shortest of time scales magnetic spins do not behave according to
existing theory. According to a research team which has formulated a new
theory of ultrafast magnetism, the spins are not coupled and move at a
different pace, dependent on the element they're part of.

In
magnetic recording media, each individual bit of information is stored
over an area containing tens of grains. Engineers have until now had
difficulty pushing beyond a one terabit per square inch limit by either
reducing grain size or reducing the grains per bit. Researchers in
Singapore have solved the problem by using something called
bit-patterned media.
