This work addresses the issue of acceleration of the long post-deposition annealing procedures typically used for obtaining the antiferromagnetic (AFM) state of the pinning film in NiMn-based spin-valve systems. It presents results on exchange biasin

Optimal conditions for depositing of high textured (111) TiN films by d.c. reactive magnetron sputtering in Ar+N2 atmosphere on Si substrates at ambient temperature are determined. For that purpose the influence of both the nitrogen flow and the disc
