  • Abstract
    Flash annealing techniques have been used to crystallize locally amorphous materials and so to obtain samples that present alternatively soft and hard zones for application in magnetic labels for security systems. We show that by adequately controlling the local flash annealing, it is possible to obtain materials with different ratios between the first and third harmonic of the induced signal in a detecting coil that can be used to codify the magnetic labels.<>
