3D Racetrack Memory Device (Max Planck)


A new technical paper titled “Three-dimensional racetrack memory devices designed from freestanding magnetic heterostructures” was published by researchers at Max Planck Institute of Microstructure Physics in Halle, Germany.

“Magnetic racetrack memory encodes data in a series of magnetic domain walls that are moved by current pulses along magnetic nanowires. To date, most studies have focused on two-dimensional racetracks. Here we introduce a lift-off and transfer method to fabricate three-dimensional racetracks from freestanding magnetic heterostructures grown on a water-soluble sacrificial release layer,” states the paper.
