The Principal Magnetic Susceptibilities of Bismuth Single Crystals

The Gouy method is used to determine the principal magnetic susceptibilities of bismuth single crystals grown by the method developed by Goetz. The specific susceptibility is shown to be a constant in all directions perpendicular to the principal crystallographic axis with a value of —1.487×${10}^{-6\mathrm{}}$. Parallel to the main axis the specific susceptibility is a minimum and has the value —1.046×${10}^{-6\mathrm{}}$. The mean is given then as —1.340×${10}^{-6\mathrm{}}$.
