Nanoneedles to increase the capacity and robustness of
digital memories

Researchers at the UAB, ICMAB and the ALBA
Synchrotron, in collaboration with the UB and ICN2, have developed
a new technique to locally modify the properties of a metamagnetic
material. The method consists of applying local pressure to the
surface of the material using nanometric needles and allows a much
more easy and local modification than current methods. The research
opens the door to a more accurate and precise control of magnetic
materials and allows to improve the architecture and capacity of
magnetic digital memories.
