Studies of magnetic properties of thin microwires with low Curie temperature

In this paper we report novel results on the fabrication and magnetic characterization of microwires with compositions Co100−x-Fe-Nix-Si-B and Co-Fe-Cr-Si-B fabricated by Taylor-Ulitovsky. Additions of Ni or Cr resulted in decreasing of the Curie temperature, TC. Few samples with low TC possessing also high GMI effect are obtained. Concrete temperature sensors applications based on the drastic change of magnetic properties in the vicinity of Curie temperature are shown.
