Abstract The longitudinal and transverse acoustic velocities of high-purity polycrystalline thulium and ytterbium have been measured by a pulse technique at a frequency of 10 MHz between 4·2 and 300°K. The variation with temperature of the Young moduli E , shear moduli G , adiabatic compressibilities K s , and Debye temperature σ d have been determined. The anomalies in the elastic properties observed in thulium were correlated with the magnetic changes known to occur in this metal at low… CONTINUE READING
