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 in 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.


Crazy for Physics launches its fifth edition

27 High School students will interact during 16 work sessions with researchers from all the participating excellence centers offering exciting experiences that explore the biggest and the smallest scales of the universe. Coordinated from the ICN2 and the IFAE, Crazy for Physics (Bojos per la Física) also involves the UAB, the ICMAB, the ICFO, the ICE, the UB and the Alba Synchrotron.



New method to produce spinel oxide nanocubes with precise size control

A research performed in the ICN2 Magnetic Nanostructures Group has resulted in a route to synthesise spinel oxide nanocubes that overcomes some of the limitations presented by previous approaches. This methodology covers a wide range of sizes and may be used for different materials. The results have been published in ACS Nano.



Micropumps as a platform for understanding chemically propelled micromotors

ICN2 researchers investigate micropumps as a window into self-propelled micromotors and beyond. In the paper published this September in Accounts of Chemical Research, lead author Dr María José Esplandiu explains how their findings are important not only to harnessing the full potential of micro- and nanomotor technologies, but also to understanding active matter systems in nature.




ICN2 in the Media: High Temperature Magnetic Stabilization of Cobalt Nanoparticles

ICREA Prof Josep Nogués is the last author of a work published in Physical Review Letters describing how low-blocking-temperature ferromagnetic Co nanoparticles become magnetically stable above 400 K (126.85 degrees Celsius) thanks to the Antiferromagnetic Proximity Effect. The work, with researchers from the University of Castilla la Mancha as first authors, gathered some attention from the media.


High Temperature Magnetic Stabilization of Cobalt Nanoparticles

A work published in Physical Review Letters, with ICREA Prof Josep Nogués, Group Leader at ICN2, as its last author, explains how an Antiferromagnetic Proximity Effect makes the Magnetic Stabilization possible above 400 K (126.85 degrees Celsius). This achievement might have crucial implications for ultrahigh density recording among other applications.
