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 Co 100− x –Fe–Ni x –Si–B and Co–Fe–Cr–Si–B fabricated by Taylor–Ulitovsky. Additions of Ni or Cr resulted in decreasing of the Curie temperature, T C. Few samples with low T C posse...

Description
Summary:In this paper we report novel results on the fabrication and magnetic characterization of microwires with compositions Co 100− x –Fe–Ni x –Si–B and Co–Fe–Cr–Si–B fabricated by Taylor–Ulitovsky. Additions of Ni or Cr resulted in decreasing of the Curie temperature, T C. Few samples with low T C 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.
