The varied undercooling achieved with the above techniques caused the formation of diverse microstructures. In electro-magnetically levitated (EML) samples (undercooling up to 127 K) mostly primary dendrites or cells with regular eutectic appeared. An anomalous eutectic made of primary CoSi2 with intergranular CoSi of different size was obtained in electrostatic levitation (undercooling from 95 K to 304 K), EML and electromagnetic levitation accompanied by the application of a static magnetic field at high undercooling up to 150 K
