Abstract
Our goal was to identify specific characteristics and inductance values in commercially manufactured toroids and subsequently reproduce them, altering those characteristics for specific applications. Based on this investigation, we tuned the properties of the [MXFe3-XO4] (where M=Mn, Ni, and/or Zn) ferrites by changing "X" and the ratio of different metals (M) for magneto-elastic pressure sensors. The value of x is changed by thermal decomposition of iron and metal oxides. The properties of the synthesized ferrites were studied by x-ray and SEM and pressed into a toroidal shape. It is then sintered in a furnace and its magnetostrictive properties investigated.
