Scientists from Ohio University has created a new spintronics memory device from plastic. It’s simply a thin strip of dark blue organic-based magnet layered with a metallic ferromagnet and connected to two electrical leads. Still, the researchers successfully recorded data on it and retrieved the data by controlling the spins of the electrons with a magnetic field. They say that the new device is a bridge between today’s computers and the all-polymer, spintronic computers that the researchers hope to eventually create.

Teams from the Johannes Gutenberg University Mainz (JGU) in Germany and Stanford University have uncovered a new quantum state of matter in Heusler compounds which they claim opens up 'previously unimagined usage possibilities'. The scientist from Mainz has shown that many Heusler compounds can behave like topological insulators (TI).

TIs have been studied in the field of solid state and material physics. Characteristic of topological insulators is the fact that the materials are actually insulators or semiconductors, although their surfaces or interfaces are made from metal - but not ordinary metal. Like superconductors, the electrons on the surfaces or interfaces do not interact with their environment - they are in a new quantum state. In contrast with superconductors, topological insulators have two non-interacting currents, one for each spin direction. These two spin currents, which are not affected by defects or impurities in the material, can be employed in the futuristic electronics field of 'spintronics' and for processing information in quantum computers.

Professor Russell Cowburn from the Imperial College in London has been awarded €2.8 million to work on spintronics, with the aim of developing new microchips that can store thousands of times more data than today’s microchips.

Professor Cowburn hopes to develop chips that hold many active components stacked on top of each other, allowing more data to be stored in the same sized chip.

Scientists from Ohio University and the University of Hamburg has captured images of atomic spin in action for the first time. They have used a custom-built microscope and cobalt atoms. The team repositioned individual cobalt atoms on a surface that changed the direction of the electrons' spin. Images captured by the scientists showed that the atoms appeared as a single protrusion if the spin direction was upward, and as double protrusions with equal heights when the spin direction was downward.

Scientists from UCLA say they created a new class of material with magnetic properties in a dilute magnetic semiconductor (DMS) system. By using a type of quantum structure, they've been able to push the ferromagnetism above room temperature. 

Ferromagnetic coupling in DMS systems, the researchers say, could lead to a new breed of magneto-electronic devices that alleviate the problems related to electric currents. The electric field–controlled ferromagnetism reported in this study shows that without passing an electric current, electronic devices could be operated and functioning based on the collective spin behavior of the carriers. This holds great promise for building next-generation nanoscaled integrated chips with much lower power consumption.

A group led by Professor Hideo Ohno in the Laboratory of Nanoelectronics and Spintronics, at Tohoku University is working to develop new integrated circuits using spintronics. The ICs store data in nonvolatile memory using magnetism (MRAM), so their standby power can be made zero. This memory utilizes the tunnel magneto-resistance effect.

Osaka's university has a Spintronics research group that is working towards MRAM and STT-RAM using several materials including Graphene. Here's a nice intro video about the group:
