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. Spintec proposed a novel ... More »

We have created an analytical model of spin waves in microscopic spin-wave waveguides in the presence of interfacial Dzyaloshinskii-Moriya interaction. By comparing to micromagnetic simulations, we have demonstrated that spatially periodic excitation sources can be used to create a uni-directional ... More »

Magnetic field mapping techniques have continuously been developed due to the necessity for determining the spatial components of local magnetic fields in many industrial applications and fundamental research. Several factors are considered for sensors such as spatial resolution, sensitivity, ... More »

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. SPINTEC has shown that this stochasticity can be almost ... More »

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. The spin current propagates from the ferromagnet into a neighboring layer if permitted by the ... More »

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. Unfortunately, the ... More »

During writing of Thermally Assisted Switching Magnetic Random Access Memory (TAS-MRAM), the torque due to a voltage pulse may be used to help writing. As part of collaboration between Spintec and Crocus Technology, we brought out that most of the influence of the spin transfer torque is exerted ... More »

A recent approach for cancer cells destruction was proposed, based on the triggering of cancer cell spontaneous death through the mechanical vibration of anisotropic magnetic nanoparticles attached to the cells membrane at low frequencies (20Hz) and in weak magnetic fields ( a few mT). The ... More »

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. However, spin dependent transport with AFs is of high interest: spin absorption lengths ... More »

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. However, it is necessary to ... More »

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. As a consequence of intermixing, ... More »
