ANOMALIES IN THE AMPLITUDE-DEPENDENT INTERNAL FRICTION AT LOW TEMPERATURES
P. FelthamBrunel University, Uxbridge, U.K.
Abstract
A minimum in the temperature dependence of the internal friction observed by Pal-Val et al. [1] in Sb single crystals of various purities between 20 and 40 K, at strain amplitudes of about 10-6, at 88 kHz, is shown to be a consequence of micro-creep, in which dislocations, possibly of the screw type, migrate through dilute solute-atmospheres.
