Notice of Removal: Effect of Some Manufacturing Factors on Magnetic Properties of Sm2Co17 Rubber Magnets

Abstract

Sm <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> Co <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">17</sub> rubber magnet is a kind of bonded magnet and can be produced using by-products obtained in the cutting process of sintered compact after Sm–Co system sintered magnets were made. These rubber magnets are still expensive, but they are effectively used for the sensors requiring a small amount of them. Their magnetic properties largely depend on the interaction between the rubber and the magnetic powder. This article describes the effect of the stearic acid and the compacting pressure on the density and magnetic properties of Sm(Co <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.6</sub> Cu <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.08</sub> Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.3</sub> Zr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.02</sub> ) <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8.35</sub> rubber magnets. In the case of 1.5 wt% of stearic acid and 850 MPa of compacting pressure, this article shows that the isotropic rubber magnet is 5.51 g/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> in density, 0.34 T in remanence, and 22.99 kJ/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> in energy product.
