Objetivo
The NANOSPIN project will study complex magnetic nanostructures consisting of a central core with one or more surrounding shells that will be functionalised to self-order on surfaces for applications in classical and quantum ultra-high density information storage. The advanced manufacturing technique we propose uses metal condensation in superfluid He droplets, which is a technology with enormous flexibility. It enables the production of core-shell particles with a free choice of ferromagnetic and antiferromagnetic core and shell materials and an arbitrary number of shells. This degree of control will allow us to engineer the internal spin configuration of an individual nanocluster and to create spin structures that have never been produced before, either naturally or artificially, with a wide range of magnetic properties. The technique will also allow us to coat the nanoparticles with a final shell to promote the ordering of arrays of the designed nanoparticles on surfaces for specific applications. This ability will have an enormous impact on the technological areas of spintronics and magnetic storage.
Examples include particles smaller than 5nm that are blocked at room temperature enabling classical data storage densities higher than 10Tb/cm2, and particles embedded in superconducting matrices in states of quantum superposition on which quantum qubits can be stored. Single-particle read/write processes and a new method to erase all data in a nanoparticle assembly using microwaves will be demonstrated. We will also assess the functionalised nanoparticles as qubits in quantum information processing systems. The programme brings together 8 partners from 2 INCO and 6 EU countries. It combines state-of-the-art instrumentation with advances in cluster production technology and will provide the fundamental understanding required to bring highly advanced technologies close to the market.
