A principle and application of Travelling Solvent Floating Zone (TSFZ) method for crystallization of La2-xSrxCuO4 and spin ladder Sr14-xCaxCu24O41 cuprate superconductors will be presented. For the later the mirror furnace was modified to ensure a stable crystal growth at oxygen pressure up to 35bar. Iron-chalcogenide single crystals Fe1+ySexTe1-x and A1-xFe2-ySe2-z (A=K, Rb, Cs) were grown by the Bridgman method. Alkali metal intercalated crystals are showing superconductivity at about 30K and coexistence of magnetism and superconductivity.
