A method of producing long single-crystals of metal and a study of the factors influencing crystal orientation and perfection
The apparatus described in the following was to serve the purpose of studying the influence on the orientation of the gradient of temperature along a single crystal during its growth, and the effect of strong magnetic fields applied at the exact point of transition of the two phases of the metal. It was found that the particular method of growing crystals of great length, developed for this investigation, was superior to any others known to the authors. It became evident that the influence of a magnetic field applied to a zone of crystallization is of such complexity that it seemed to be better to describe these effects in a separate paper, especially since the method has practically nothing to do with the special purpose, and therefore, may be of more general interest.
