Abstract

Apparatus for the measurement of magnetic anisotropy has been constructed. It is based upon a method first developed by Krishnan in which the torsional force due to the twist on a fine quartz fiber is used to measure the couple acting on the crystal resulting from its anisotropy. By this means the diamagnetic anisotropy of iodoform, arsenic triiodide and potassium chloroplatinite were measured. The results obtained with the last named compound indicated the presence of ferromagnetic impurities. A table of the diamagnetic anisotropy of organic compounds measured to January 1948 has been compiled.
