Abstract:
The influence of post-processing conditions on the magnetic properties of amorphous and nanocrystalline microwires has been analyzed, paying attention on the effect of magnetoelastic and magnetocrystalline anisotropies on the hysteresis loops of Fe-, Ni- and Co-rich microwires. We demonstrated that the selection of appropriate chemical composition and geometry of as-prepared microwires and appropriate post-processing consisting of annealing or glass-coated removal allow tuning of magnetic properties of glass-coated microwires. Magnetic hardening of the microwires can be achieved by the devitrification of Fe-Pt-Si microwires.
