      (IEEE, 2009-10)
      In this paper, we examine the problems related to orthogonal fluxgates realized using magnetic microwires as core. Starting from a description of orthogonal fluxgates evolution, we give a theoretical analysis of the problems ...
    • Sensitivity and Noise of Wire-Core Transverse Fluxgate 

      Autor: Ripka, Pavel; Butta, Mattia; Jie, Fan; Li, Xiaoping
      (IEEE, 2010-02)
      Fluxgate sensors with cores made of amorphous microwire have low sensitivity due to the small cross-sectional area of the wire. Previous studies with multiwire cores have shown nonlinear increase of sensitivity with number ...
    • Two-Domain Model for Orthogonal Fluxgate 

      Autor: Butta, Mattia; Ripka, Pavel
      (IEEE, 2008-11)
      In this paper a new model for orthogonal fluxgate is presented. A first attempt to explain the working principle of the orthogonal fluxgates was done in the 1970's. We show that this model does not work well on recently ...
