We have recently reported that pure spin conductors could behave as nonlinear component in the high power regime, hereby opening up considerably the realm of functions realizable with magnetic materials. An additional feature is that these are continuously tunable by an external magnetic field.

Radiation robust circuit design for harsh environments like space is a big challenge for IC design and embedded systems. As circuits become more and more complex and CMOS processes get denser and smaller, their immunity towards particle strikes decreases drastically.

The writing in conventional magnetic memories based on magnetic tunnel junctions (STT-MRAM) is intrinsically stochastic : a large amplitude thermal fluctuation is required to trigger the siwthing of the storage layer magnetization.

A fluctuating magnetic order allows more spins to pass through an interface. Bringing a ferromagnetic layer to resonance creates non-equilibrium magnetization dynamics which generates a spin current.

Magnetic devices made from the same thin film and subjected to the same electric excitation switch opposite to each other due to their different shape. The magic about the art of paper folding is that from the same sheet of paper one can create so many different objects.

In spintronics, the spin dependent transport properties of ferromagnets (Fs) lie at the heart of devices working principles. Conversely, antiferromagnets (AFs) are so far used for their magnetic properties only.

In order to enhance the tunnel magnetoresistance (TMR) of magnetic tunnel junctions with perpendicular anisotropy the thicknesses of the electrodes on both sides of the MgO barrier have to be optimized.

Usually, magnetic tunnel junctions consist of electrodes made of an alloy of cobalt, iron and boron (CoFeB) and a tunnel barrier in magnesium oxide (MgO). To bring perpendicular anisotropy to such structures, multilayers of cobalt and platinum (Co/Pt) may be used.

Spintronics applications use ferromagnetic(F)/antiferromagnetic(AF) exchange bias (EB) interactions to set the reference direction required for the spin of conduction electrons. They therefore may involve layers intermixing originating from F/AF interfaces.

In May, at the "International Memory Workshop" organized by the IEEE in California, Spintec and Crocus Technology presented the first demonstration of magnetic memory cells capable of performing a logic function.
