The giant magnetoresistance in a ferromagnetic suspension

A short review of the magnetoresistance magnitudes of various types of materials is given in the introduction of the article. It is followed by a description of the way a special ferromagnetic suspension is produced. The suspension consists of silicon steel particles with dimensions of 0.15-0.20 mm, and graphite particles with dimensions not bigger than 5 x 10(-7) m. The particles with given dimensions were dispersed in the non-polymerized epoxy resin. An experimental set-up construction was described and the results of magnetoresistance measurements of this type of suspension with different contents of silicon steel and graphite particles were shown. The obtained results are discussed in the final part of the article. (C) 1998 Published by Elsevier Science S.A. All rights reserved.
