RESEARCH AND DEVELOPMENT ON ADVANCED GRAPHITE MATERIALS. VOLUME 39. DIAMAGNETIC SUSCEPTIBILITY OF GRAPHITE BY THE FARADAY METHOD

Abstract

The diamagnetic susceptibility of several types of graphite, both single and polycrystalline, was investigated at room temperature by the Faraday method. This method measures the entire sample; it can be used to obtain the three com ponents for a trace; and it can account for ferromagnetic impurities. The susceptibility representing the contribution of the truly graphitic portion of a sample, ranges from -22.8 times 10 to the - 6th power emu/gm for single crystals down to -19.1 times 10 to the 6th power emu/gm for grade ZTA graphite. Direct orientation measurements showed that both single crystals and polycrystals display a true cosine squared dependence, modified in amplitude by the degree of preferred crystallite orientation. These results are justified theoretically.
