Table 1. Numerical data of the diamagnetic grains studied in the present report. Here, m and χDIA denote the mass of the sample, and the diamagnetic susceptibility per unit mass, respectively. The samples were cut from a synthetic block having a purity of 99.99%. The χDIA values of graphite-1 and bismuth-1 were measured in a previous study (Hisayoshi et al., 2011).
