Mg-assisted autoclave synthesis of RB6 (R = Sm, Eu, Gd, and Tb) submicron cubes and SmB6 submicron rods

Submicron crystalline rare-earth hexaborides (RB6; R = Sm, Eu, Gd, and Tb) have been successfully prepared by a facile one-step solid-state reaction of RCl3·OH2O, B2O3, and Mg powder in an autoclave at the relatively low temperature of 500°C. By controlling the reaction, conditions, submicronsized cubes (RB6) and rod- and needlelike SmB6 are obtained. The possible growth mechanism of the 1D SmB6 structures has also been discussed. The XRD patterns of the products show that all of the hexaborides can be indexed to a cubic phase with high crystallinity and high purity. The field-emission scanning electron microscopy (FESEM) and TEM images display their cube-, rod-, and needlelike morphologies. The selected-area electron diffraction (SAED) patterns reveal the single-crystalline nature of the products.

Large crystal structure distortion in DyB6 studied by X-ray diffraction

A large magnetoelastic coupling induces a lattice distortion of a rhombohedral type in DyB6. Below the quadrupolar ordering temperature TQ=31K the cubic and the distorted phases coexist. The cubic phase disappears at 23K, which was identified as the magnetic ordering point TN. In the magnetic phase the distortion (dl/l)111 increases monotonically with decreasing temperature and reaches the value of 9 × 10-3 at 8 K, which is one of the largest value known for cubic compounds.

Thermodynamic functions for heavy rare-earth hexaborides as measured by calorimetry in the temperature range from 5 to 300 K

The molar heat capacities of gadolinium, terbium, and dysprosium hexaborides were measured over the temperature range 5-300 K. The temperature dependences and the standard values of the enthalpy, entropy, and the Gibbs energy were calculated by taking into account the nuclear contribution to the heat capacity.

Single Crystal Growth and Properties of Incongruently Melting TbB6, DyB6, HoB6, and YB6

Details of the single crystal growth of incongruently melting TbB6, DyB6, HoB6, and YB6using a crucible-free vertical floating zone method are reported. Magnetic susceptibility is reported and discussed. It is suggested that antiferro-quadrupolar ordering occurs in DyB6between 30 and 25.6 K.
