Superconducting properties of HoNi2B2C single crystals — •Dmitri Souptel, Günter Behr, Wolfgang Löser, Konstantin Nenkov, and Günter Fuchs — IFW Dresden, Helmholtzstr. 20, 01171 Dresden

High-quality single crystals of HoNi2B2C intermetallic compounds have been grown by a floating zone technique with optical heating. Depending on small composition variation and the temperature of heat treatment single crystalline HoNi2B2C samples show a variety of properties: plain superconductivity (Tc about 8 K), re-entrant superconductivity (Tc about 8 K and loss of superconductivity between 4 - 6 K due to 2 incommensurate magnetic ordering) and normal conducting behaviour. Origins of different superconducting properties and their anisotropic behaviour are related to crystal composition, lattice parameters and changes of lattice site occupancies of the composing elements.
