Abstract
The magnetic susceptibility of crystalline tellurium, in the range between ambient and liquid air temperatures, has been measured by means of the Sucksmith’s ring balance, and the magnetic anisotropy of a single crystal of tellurium has also been studied by the torsion magnetometer method in the same temperature range. The susceptibility of purest crystalline tellurium is diamagnetic, being appraised at−0.301×10−6 c.g.s.e.m.u. per gr, and remains constant from room temperature down to liquid air temperature. A single crystal, however, shows the difference in the susceptibility between the directions perpendicular and parallel to the principal hexagonal axis, that is to say, Δχ=χ⊥−χ\varparallel amounts to 0.458×10−8 at 78°K and rises linearly to 0.717×10−8 at 295°K. Whence it follows that the magnetic anisotropy, χ\varparallel⁄χ⊥, is evaluated to be 1.015 at 78°K and 1.024 at 295°K.
