ChemInform Abstract: Crystal Growth and Magnetic Characterization of a Tetragonal Polymorph of NiNb2O6.

Abstract Single crystals of NiNb 2 O 6 are grown in an optical floating zone furnace using a 1.2% molar excess of NiO in a sintered columbite rod as well as a pure O 2 atmosphere and a growth rate of 25 mm/h.
