Popis: The temperature dependence of Young's modulus ( E c and E b ) and the internal friction have been measured in a high-purity gadolinium single crystal along the c - and b - axis in the temperature range of 4.2–350 K at the frequencies of 800–1200 Hz. At 4.2 K the values of E c and E b are equal to 7.25×10 11 and 6.14×10 11 dyn/cm 2 , respectively. The lattice part of Young's modulus has been calculated. The origin of Young's modulus anomalies at the Curie temperature and in the temperature region near 140 K are discussed.
