Abstract

The single crystals of a. new quaternary compound ErRh2B2C have been obtained as thin plates in an atmosphere of helium by the flux method using molten copper. The single crystals show golden-colored luster and the maximum size obtained is about 1.0 × 1.0 × 0.02 mm3. This compound belongs to a tetragonal system and seems to be a derivative of ThCr2Si2 type; lattice parameter: a=0.36848 (2) nm, c=1.05520 (3) nm, V=1.4327 × 10-28 m3 and Z=2. The electrical resistivity parallel to the a-b plane decreases monotonically with decreasing temperature, but no superconductivity is observed down to 1.5K. The residual resistivity ratio, ρ(273 K)/ρ(1.5 K), is 1.38. Similar type new compounds of RRh2B2C were obtained for R=La-Er (except Eu and Tm) and Y by arc-melting synthetic method.
