Magneto-transport in granular ribbons at high magnetic fields

Magneto-transport in granular ribbons at high magnetic fields

We have measured the bulk and surface magnetisation and magnetoresistance of granular Co 10Cu 90 ribbons treated with isochronous anneals, from helium to room temperature and at high magnetic fields. The magnetoresistance of these materials can be larger than 15% at room temperature and at high magn...

Description
Summary:We have measured the bulk and surface magnetisation and magnetoresistance of granular Co 10Cu 90 ribbons treated with isochronous anneals, from helium to room temperature and at high magnetic fields. The magnetoresistance of these materials can be larger than 15% at room temperature and at high magnetic fields. We show that interparticle interactions are needed for a complete description of the experimental results.
