Abstract
A complex relative movement in a direction transverse to the crystal draw direction is imparted at the interface between the growing crystal bar and a melt of the crystallizable material by controlled electrical energization of a radial stabilizer acting upon the magnetizable core by which either the bar or the crucible or a supply bar for the material, or both, can be suspended.
