Popis:	Traveling magnetic fields (TMFs) can be used to control the shape of the crystal–melt interfaces at crystal growth from melt. Here, we present the numerical results of a systematic study on the influence of a TMF generated by a KRIST MAG ˜ ® heater-magnet module on the interface curvature of different materials varying in their electrical conductivity in a wide range (5×10 1 to 1.7×10 7 S/m) such as Ge, Si, CdTe, BaF 2 and YAG. Materials were compared in the same design of environment by using results obtained for Ge as a reference. For the rescaling of the growth equipment, non-dimensional criteria were applied. Positive slightly convex crystal–melt interface can be obtained for all materials studied using moderate electrical currents.
