Heat capacity (150–300 K) and anisotropic magnetic susceptibility (5–300 K) of single-crystal La2CuO4+x

Magnetic susceptibility and heat capacity measurements of single crystal TbMnO3.

Measurements of the magnetic susceptibility χ and heat capacity C on single crystals of the multiferroic TbMnO3 are presented. A non-magnetic isostructural compound, LaGaO3, was used to isolate the magnetic component of the heat capacity. An anisotropic magnetic susceptibility, deviations from Curie-Weiss behaviour and a significant magnetic entropy above the antiferromagnetic ordering temperat...

Crystal Structure of Nonaaquayttrium(III) Bromate at 100 K

The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...

Coexistence of superconductivity (Tc= 55 K) and antiferromagnetism TN= 230 K) in YBa2CuS06. 66 single crystal

2014 Neutron scattering and susceptibility measurements on a YBa2CU3O6.55 single crystal show that the antiferromagnetic long range order coexists with superconductivity. The oxygen content has been determined by a complete neutron diffraction structure analysis. Evidence for superconductivity below Tc= 55 K has been obtained from magnetization measurements. Magnetic Bragg scattering has been o...

MAGNETIC SPECIFIC HEAT OF CoCl2.2 PYRAZINE BELOW 2 K

Absorptivity of Single-Crystal Yttrium at 4.2 K

Measurements of the absorptivity of single crystals of Y were made between 0.15 and 4.4 eV at 4.2 K. Polarized radiation was used with the electric vector parallel or perpendicular to the c^ axis of the crystal. The observed structures in the absorptivity were interpreted on the basis of band calculations for Sc, Re, and Gd and qualitative agreement was found between the band structures and the...
