Title: Single crystal growth and characterization of Na{sub x}Ln{sub 1−x}MoO{sub 4}, Ln=La, Ce, Pr, Nd, Sm, and Eu (x=0.397–0.499)

Abstract

Single crystals of La{sub 0.516(3)}Na{sub 0.484(3)}MoO{sub 4}, Ce{sub 0.512(2)}Na{sub 0.488(2)}MoO{sub 4}, Pr{sub 0.502(2)}Na{sub 0.498(2)}MoO{sub 4,} Nd{sub 0.501(2)}Na{sub 0.499(2)}MoO{sub 4}, Sm{sub 0.509(2)}Na{sub 0.491(2)}MoO{sub 4}, and Eu{sub 0.603(2)}Na{sub 0.397(2)}MoO{sub 4} were grown for the first time out of an alkali metal halide eutectic flux. All compounds crystallize in the tetragonal space group I4{sub 1}/a. UV/Vis measurements show the presence of an absorption edge for all compounds except Eu{sub 0.603(2)}Na{sub 0.397(2)}MoO{sub 4}. The temperature dependence of the magnetic susceptibility was measured for all compounds and found to be paramagnetic across the entire 2–300 K temperature range measured. - Graphical abstract: Single crystals of La{sub 0.516(3)}Na{sub 0.484(3)}MoO{sub 4}, Ce{sub 0.512(2)}Na{sub 0.488(2)}MoO{sub 4}, Pr{sub 0.502(2)}Na{sub 0.498(2)}MoO{sub 4,} Nd{sub 0.501(2)}Na{sub 0.499(2)}MoO{sub 4}, Sm{sub 0.509(2)}Na{sub 0.491(2)}MoO{sub 4}, and Eu{sub 0.603(2)}Na{sub 0.397(2)}MoO{sub 4} were grown for the first time out of an alkali metal halide eutectic flux.

  • Single crystals of uranium intermetallic compound UCo0.5Sb2 were grown by means of the antimony-flux technique. The characterization of the samples has been carried out utilizing single crystal X-ray diffraction and magnetization measurements. UCo0.5Sb2 is found to crystallize in the tetragonal HfCuSi2-type structure, space group P4/nmm with Z=2 formula units per cell, and the lattice parameters a=0.4300(1) and c=0.8958(2)nm. The refinement of the occupancy parameters and the energy dispersive X-ray analysis have indicated a distinct deficiency on the cobalt sites. The results of magnetization measurements showed that UCo0.5Sb2 orders ferromagnetically below 65K with a huge magnetocrystalline anisotropy with the c directionmore » being the easy magnetization axis.« less
  • A method is described for growth of single crystals of NiSe{sub 2} from the elements. The crystals are approximately 5 mm on an edge and free of secondary phases or pores if care is taken in compositional control, in repetitive regrindings, and in slowly removing the sample from the furnace. The electrical and magnetic properties of the crystals are briefly described; no prior measurements of resistivity have been reported below room temperature. A theoretical analysis shows that NiS{sub 1.93} is a metal exhibiting weak correlation effects.

  • Single crystals of Zn- and Ni-substituted YBa{sub 2}Cu{sub 4}O{sub 8} with {Tc}=80-20 K for Zn and {Tc}=80-0 K for Ni have been grown from a BaO-CuO flux at 1090 C under 600 bar of O{sub 2}. Crystals grown in yttrium stabilized ZrO2 crucibles do not show contamination from the crucible material. The effective distribution coefficients for Zn and Ni are 0.3 and 1, respectively. The solubility limits are around 2% for Zn and above 6.5% for Ni. Single-crystal X-ray diffraction is used to characterize the crystal quality but it lacks the sensitivity to conclusively differentiate the site preference for smallmore » amounts of substituted ions. All crystals show sharp superconducting transitions with {Delta}{Tc} gradually increasing with decreasing {Tc}.« less
  • Single crystals of Cu13Ba were successfully grown out of Ba–Cu self flux. Temperature dependent magnetization, M (T ), electrical resistivity, ρ(T)ρ(T), and specific heat, Cp(T)Cp(T), data are reported. Isothermal magnetization measurements, M(H)M(H), show clear de Haas-van Alphen oscillations at T = 2 K for applied fields as low as View the MathML sourceμ0H=1T. An anomalous behavior of the magnetic susceptibility is observed up to T ≈ 50 K reflecting the effect of de Haas-van Alphen oscillations at fairly high temperatures. The field- and temperature-dependencies of the magnetization indicate the presence of diluted magnetic impurities with a concentration of the ordermore » of 0.01 at.%. Accordingly, the minimum and lower temperature rise observed in the electrical resistivity at and below T = 15 K is attributed to the Kondo-impurity effect.« less
