Abstract

Neutron Diffraction and Observation of Superconductivity for Tungsten Borides, WB and W2B4. -The title compounds are investigated by neutron diffraction and magnetic measurements. WB becomes superconducting at 4.3 K in the tetragonal modification (space group I4/amd) and at 2.8 K in the orthorhombic modification (space group Cmcm). W2B4 (formerly known as W2B5) also shows a superconducting transition at 5.4 K, which is suppressed for small grain samples. -(KAYHAN, M.; HILDEBRANDT, E.; FROTSCHER, M.; SENYSHYN, A.; HOFMANN, K.; ALFF, L.; ALBERT*, B.; Solid State Sci.
