<p><span>The bulk </span>magnetic susceptibilities<span> of single </span>gallium<span> crystals and </span>polycrystalline<span> </span>gallium<span> spheres were </span>measured<span> at 25°C. The following </span>anisotropic<span> </span>diamagnetic<span> </span>susceptibilities<span> were found: </span><i>a</i><span> axis (−0.119±0.001)×10</span><sup>−6</sup><span> emu/g, </span><i>b</i><span> axis (−0.416±0.002)×10</span><sup>−6</sup><span> emu/g, and </span><i>c</i><span> axis (−0.229±0.001) emu/g. The </span>susceptibility<span> of the </span>polycrystalline<span> spheres, assumed to be the average value for the bulk </span>susceptibility<span> of </span>gallium,<span> was (−0.257±0.003)×10</span><sup>−6</sup><span> emu/g at 25°C, and (−0.299±0.003)×10</span><sup>−6</sup><span> emu/g at −196°C. The </span>susceptibility<span> of liquid </span>gallium<span> was (0.0031±0.001)×10</span><sup>−6</sup><span> emu/g at 30°C and 100°C. Rotational diagrams of the </span>susceptibilities<span> in the three orthogonal planes of the unit cell were not sinusoidal. The </span>anisotropy<span> in the </span>single crystals<span> was presumably caused by the partial overlap of </span>Brillouin<span> zone boundaries by the Fermi‐energy </span>surface.<span> The large change in </span>susceptibility<span> associated with the change in state was attributed to the absence of effective mass influence in the liquid state.</span></p>
