MAGNETIC MICROWIRES FOR GMI-BASED MAGNETIC SENSORS IN AVIATION

Abstract

This article is dedicated to the study of magnetic properties of glass-coated ferromagnetic microwires and especially to giant magneto-impedance (GMI) effect. Magnetic sensors based on the GMI effect are suitable candidates for use in many sensor devices. Those devices can be find in aviation industry, on airports and in aircrafts. Some of applications are presented in third chapter. The main part of the article is result of experiment, which examines GMI effect in amorphous Co-Fe microwire. This experiment was carried out at two different frequencies (1 MHz and 1,6 MHz).
