Abstract

Single crystals of Na2Ti2Sb2O have been grown by NaSb flux method. It crystallizes in platelet morphology with dark silver color. The growth conditions are optimized and crystal structure has been analyzed by single crystal X-ray diffraction at 88.7, 120.0 and 150.0K. The structure analysis result shows that there is a non-linear change in temperature-dependent lattice parameters suggesting that previously reported anomaly in temperature-dependent magnetization and electrical resistivity of polycrystalline samples around 120K is associated with the structure distortion. Temperature-dependent magnetic susceptibility of a single crystal sample grown by NaSb flux method also exhibits a sharp transition around 120K confirming that this anomaly is intrinsic to Na2Ti2Sb2O.
