Abstract in another language
Structure data and variation of lattice parameters of single crystals of {RNi2B2C} (R=Y, Tb, Dy, Ho, Er, Lu) have been investigated as a function of temperature. Eight quaternary and pseudo-quaternary compounds, respectively, were investigated between 90 and 360 K. Lattice parameters a and unit cell volumes {VUC} increased for all compounds with increasing temperature, while the axial ratios c/a of the unit cell parameters decreased. The most notable observation is a minimum in the temperature dependence of the lattice parameter c, which shifts towards lower temperatures with increasing atomic number {ZR} of the rare earth element. Coefficients of linear thermal expansion for YNi2B2C, for example, vary between αa=4.71×10−6 K−1 (100 K)–13.0×10−6 K−1 (300 K) and αc=−9.93×10−6 K−1 (100 K)–8.24×10−6 K−1 (300 K). Bulk expansion β varies between β=0.73×10−5 K−1 (100 K) and 2.78×10−5 K−1 (300 K).
