Examining domain walls in magnetic nanowires
Magnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, ...

Magnetic symmetry is not just like looking in a mirror
When you think about how rapidly computers filled our homes, our cars and even ourselves through watches and earpieces, it might be hard to believe that there is a massive gap between computer's processing power and the speed, ...

Speed of magnetic domain walls found to be fundamentally limited
A team of researchers from MIT and several institutions in Korea has found that the speed of magnetic domain wall movement is fundamentally limited. In their paper published in the journal Science, the group describes testing ...
Studying chiral exchange drag and chirality oscillations in synthetic antiferromagnets
A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Topological defects could be key to future nano-electronics
The reason that a magnet sticks to the fridge is that electronic spins or magnetic moments in the magnetic material spontaneously align or order in one direction, which enables it to exert an attractive force to the steel ...

Researchers find ferrimagnets could be used to speed up spintronics devices
A team of researchers from MIT, the Max-Born-Institut, Technische Universität Berlin and Deutsches Elektronen-Synchrotron (DESY) has found that using ferrimagnets instead of ferromagnets could theoretically speed up spintronics ...
Three distinct variants of magnetic domain walls discovered in helimagnet iron germanium (FeGe)
Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). Their results have been published in Nature Physics. Researcher Dennis Meier, an associate professor at ...

Bit data goes anti-skyrmions
Today's world, rapidly changing because of "big data", is encapsulated in trillions of tiny magnetic objects - magnetic bits - each of which stores one bit of data in magnetic disk drives. A group of scientists from the Max ...
