S. Bednarek, The gaint transverse magnetoresistance in a magnetorheological suspension with a conducting carrier, J MAGN MAGN, 202(2-3), 1999, pp. 574-582
In this article there has been described a method of production and investi
gation of the transverse magnetorheological suspension with a conducting ca
rrier. The suspension consisted of ferromagnetic particles obtained from st
eel with 4% of silicon steel content. The sizes of the ferromagnetic partic
les were in the range 0.15-0.20 mm. These particles were dispersed in a car
rier of a non-polymerised epoxy resin and graphite particles not exceeding
0.5 mu m in size. Six samples of such suspensions with a different content
of silicon steel and graphite particles were produced. These samples were p
laced in a magnetic held of 0-1.1 T and their transverse magnetoresistance
measured. In 1.1 T it was found that the relative changes of resistivity of
the samples was in the range 61-97.9%. When the held was switched off, it
was observed that the hysteresis of resistivity reached values ranging from
26.5 to 73.7%. (C) 1999 Elsevier Science B.V. All rights reserved.
