英文摘要High quality and large-size single crystals of CaTi2 O-4 were prepared by the molten salt flux method. The X-ray diffraction and the EDS results showed that all the CaTi2 O-4 crystals have the rom temperature lattice parameters a = 9. 781 angstrom, b = 9. 966 angstrom and c = 3. 148 angstrom, and all the samples have perfect stoichiometric composition. Through the magnetic susceptibility measurement, we first obtained the Van-Vleck paramagnetic parameter of CaTi2 O-4 of 6. 85 x 10(-5) cm(3)/mol, and Cure-Weiss temperature of -0. 44 K, revealing that CaTi2 O-4 is a weak ferromagnetic compound. Further more, the existence of Ti-Ti dimer was confirmed by anisotropy measurement, the structure and direction of the antiferromagnetic dimer chains were also determined.
